2. Determine from the License and Activation Key whether you should install
Stata/MP, Stata/SE, Stata/IC, or Small Stata.
Stata for Windows installation
1. Insert the installation media.
2. If you have Auto-insert Notification enabled, the installer will start au-
tomatically. Otherwise, you will want to navigate to your installation
media and double-click on Setup.exe to start the installer.
3. Go to page 3for detailed instructions about the rest of the installation.
Stata for Mac installation
1. Insert the installation media.
2. Open the installation media on the Desktop, and double-click on the
Installer application.

Installing Stata for Windows
Upgrade or update?
If you are using an earlier Stata release and you are upgrading to Stata 13, or
if you have never installed Stata before on this computer, you need to read
this Installation Guide. If you have already installed Stata 13 and you would
like to install the latest updates to Stata 13, please refer to [GSW] 19 Updating
and extending Stata—Internet functionality.
Upgrading to Stata/MP, Stata/SE, or Stata/IC
If you have already installed a flavor of Stata 13 and have purchased an
upgrade to Stata/MP, Stata/SE, or Stata/IC, run the installer again. Check
Modify, click on Next, and choose the flavor(s) of Stata you wish to install.
Your existing copy will not be affected.
Make sure that you have your License and Activation Key before doing this.
After installation, you will immediately want to update Stata because your
executable will most likely be out of sync with your ado-files.
Before you install
Before you begin the installation procedure:
1. Make sure you have the Stata installation media.
2. Make sure you have a License and Activation Key.
3. Determine from the License and Activation Key whether you should install
Stata/MP, Stata/SE, Stata/IC, or Small Stata.
4. Decide where you want to install the Stata software. We recommend
C:\Program Files (x86)\Stata13 on 64-bit Windows and
C:\Program Files\Stata13 on 32-bit Windows.
5. If you already have an old version of Stata on your system, decide
whether you want to keep it or uninstall it. We do not recommend
having more than one version of Stata installed at a time, because it can
cause confusing file-association behavior.

Installation
Have your Stata License and Activation Key with you.
1. Insert the installation media.
2. If you have Auto-insert Notification enabled, the installer will start au-
tomatically. Otherwise, you will want to navigate to your installation
media and double-click on Setup.exe to start the installer.
3. You might be asked to verify that you want to install the software; if
so, confirm that you wish to do so.
4. The Stata 13 Installation Wizard will start. Proceed as you would with
any other software installation.
5. Read and accept the software license agreement to proceed with the
installation.
6. The installer will display options for personalizing your installation and
making Stata accessible to all users who share your computer. The default
choices are probably what you want. If not, make any necessary changes,
and click on Next.
7. At the Select Executable step, you can choose which type and flavor of
Stata to install.
a. Choose the flavor of Stata that matches your License and Activation
Key.
b. If you have a 64-bit computer with 64-bit Microsoft Windows
installed, you must install a 64-bit version. For network instal-
lations which require both 64-bit and 32-bit versions for clients,
after completing the installation of the 64-bit version, run the
installer again, as described in step 11 below, and install the
32-bit version.
c. If you have a 32-bit computer, you may only install a 32-bit
version of Stata.
8. The installer will ask you where you want to install Stata.
a. We recommend that you choose the default directory.
b. If you want to install Stata on a network drive, you will need a
network license. You can install Stata from the server, or if you
have the appropriate privileges, you can install Stata directly to
the network drive.
c. When you have chosen an installation directory, click on Next.
[ IG ] Installing Stata for Windows 5
9. The installer will then ask you where you want to set the default working
directory.
a. The default working directory is the default location for your
datasets, graphs, and other Stata-related files.
b. We recommend that you choose Use Each User’s Documents Folder.
c. When you have chosen a default working directory, click on
Next to begin the installation.
10. When the installation is complete, click on Finish to exit the installer.
11. If you would like to modify your installation or install other flavors of
Stata that are below the flavor of your license, you can run the installer
a second time. It will bring up the Application Maintenance dialog. Check
Modify, and click on the Next button. You can then choose the flavor(s)
of Stata that you would like to add.
If you would like to install Stata by using the command line, please consult
http://www.stata.com/support/faqs/win/autoinstall.html. Do this even if you
have installed previous versions of Stata via the command line, because the
arguments have changed.
Initialize the license
You now need to start Stata so that you can initialize the license. Go to the
Stata 13 program group in the Start menu, and click on the version of Stata
you installed.
The first time that you start Stata, it will prompt you for the information on
your License and Activation Key. You must enter something for all fields in
the dialog before you can continue. The code and authorization are not case
sensitive. If you make a mistake typing the codes, you will be prompted to
try again.
6[ IG ] Installing Stata for Windows
If you get the message “The serial number, code, and authorization are
inconsistent”, try the initialization again. Be careful when typing your code
and authorization. Anything that looks like “o” is the letter oh, anything like
“0” is a zero, anything like “1” is the number one, and anything like “L” is
the letter el.
Important: Do not lose your License and Activation Key. You may need it
again in the future.
Update Stata if necessary
StataCorp releases updates to Stata often. These updates may include new
features and bug fixes that can be automatically downloaded and installed by
Stata from the Internet. There may be updates to Stata more recent than the
version of Stata on your installation media.
The first time Stata is launched, a dialog will open asking you if you would
like to check for updates now. Click on OK to do so. If an update is available,
follow the instructions. If you have trouble connecting to the Internet from
Stata, visit http://www.stata.com/support/faqs/web/ for help.
By default, automatic update checking is enabled. This ensures that your
Stata is up to date, it is convenient, and it causes no problems even if you are
not connected to the Internet. If you disable automatic update checking, it is
a good idea to periodically check for updates to Stata. See [GSW] 19 Updating
and extending Stata—Internet functionality for more information about updating.
[ IG ] Installing Stata for Windows 7
Register your copy
Make sure that your copy of Stata is registered. As a registered Stata user,
you are entitled to free technical assistance should you have any questions,
and we will keep you informed of any new products or advancements that
have been announced. To register your copy of Stata, fill out the online
registration form at http://www.stata.com/register/, or return the registration
card that came with your Stata software.
Creating network shortcuts
If you installed Stata on a network drive, you will need to create shortcuts
on the workstations that will be using Stata.
1. Mount the network drive that Stata is installed on from a workstation.
Right-click on the Desktop or on the Windows Start menu, and select
New > Shortcut. Type the path for the Stata executable into the edit
field, or click on Browse... to locate it. Enter “Stata” for the name of the
shortcut.
2. Once a shortcut for Stata has been created, right-click on it, and select
Properties. Set the default working directory for Stata by changing the
Start in field to a local drive that users have write access to. This is
where Stata will store datasets, graphs, and other Stata-related files. If
the workstation will be used by more than one user, consider changing
the Start in field to the environment variable %HOMEDRIVE%%HOMEPATH%.
Doing so will set the default working directory to each user’s home
directory.
Other ways to start Stata
You can start Stata in multiple ways:
•From the Start menu.
•Double-click on its application icon (as with any other application).
•Double-click on a Stata do-file. See [GSW] 13 Using the Do-file Editor—
automating Stata and [U] 16 Do-files for more information.
•Double-click on a Stata data file. Stata data files are files created by Stata
and have the extension .dta. When you double-click on a Stata data file,
Stata is started and the data file is loaded into Stata; see [GSW] 5 Opening
and saving Stata datasets.
If you experience any problems when trying to start Stata, see [GSW] A Trou-
bleshooting Stata. (We are assuming that you have successfully installed Stata
and have initialized the license. Please see page 24 for how to access the
PDF documentation from outside Stata.)
8[ IG ] Installing Stata for Windows
Exiting Stata
To exit Stata, select Exit from the File menu or press Alt+F4. If you have
made any changes to the data in your dataset, including creating a new
dataset, you will be prompted to save the changes.
If you exit Stata by typing the equivalent exit command, you will see the
following in the Results window if you have made changes to your data:
 
no; data in memory would be lost
r(4);
 
If you would like to save your changes, you could save the dataset as you
save any other file by using File > Save or Ctrl +S. You can also save the
dataset by typing save filename. You could then type exit again, and Stata
will exit. If you do not wish to save your changes, you can force Stata to
exit without saving the dataset by typing exit, clear.
Verifying installation
If you need to create a report to verify that Stata has been installed properly,
point your browser to http://www.stata.com/support/installation-qualification/.
There you will find instructions for downloading and using the Stata Installation
Qualification Tool (IQT). The tool will verify your installation not only after
you initially install Stata, but also after every update you apply.
Installing Stata for Mac
Upgrade or update?
If you are using an earlier Stata release and you are upgrading to Stata 13, or
if you have never installed Stata before on this computer, you need to read
this Installation Guide. If you have already installed Stata 13 and you would
like to install the latest updates to Stata 13, please refer to [GSM] 19 Updating
and extending Stata—Internet functionality.
Upgrading to Stata/MP, Stata/SE, or Stata/IC
If you have already installed a flavor of Stata 13 and have purchased an
upgrade to Stata/MP, Stata/SE, or Stata/IC, run the installer again and select
Add Stata/MP,Add Stata/SE, or Add Stata/IC for the Installation Type.
Make sure that you have your License and Activation Key before doing this.
After installation, you will immediately want to update Stata because your
executable will most likely be out of sync with your ado-files.
Warning against multiple Stata applications
We recommend against having more than one Stata application installed on
the same computer, because it can confuse the Finder. Why? Because when
you double-click on a Stata file, the Mac may choose the wrong Stata to run.
You will not be able to predict which one will start. If you typically do not
start Stata by double-clicking on Stata files, you can have multiple versions,
but be forewarned that the first time you start Stata by double-clicking, you
may be confused.
Before you install
Before you begin the installation procedure:
1. Make sure you have the Stata installation media.
2. Make sure you have a License and Activation Key.
3. Determine from the License and Activation Key whether you should install
Stata/MP, Stata/SE, Stata/IC, or Small Stata.

Installing Stata for Unix
Installation overview
The outline of the installation process is as follows:
1. Ensure that you have the Stata installation media and the License and
Activation Key.
2. As superuser, create the directory in which you want to install Stata.
3. Change to that directory and run the installation script that is on the
Stata installation media.
4. Follow the instructions during the installation process.
5. Once the installation is complete, enter your license codes.
The details for each of these steps are below, with some pointers for
troubleshooting.
Find your installation media and license
You should have received the installation media and a License and Activation
Key. You will need both to install Stata. The codes in the License and Activation
Key are necessary for initializing the Stata software.
Obtain superuser access
You must be logged in as superuser (root) to install Stata. For varieties of
Unix that disable the root account by default, issue either the command sudo
su - or the command su - to run as superuser during the installation. The #
prompt below indicates that you are running as superuser.
Create a directory for Stata
We recommend that you install Stata in /usr/local/stata13.
If you would like the path to the executables as seen by users to remain stable
as you upgrade Stata in the future, you can create a symbolic link (type man
ln for more information) from /usr/local/stata13 to /usr/local/stata:
# ln -s /usr/local/stata13 /usr/local/stata
If you wish to install Stata in a different directory, you are free to do so.
13
14 [ IG ] Installing Stata for Unix
Users who want to access Stata must modify their .profile or .cshrc or
.login shell start-up scripts to include the Stata installation directory in their
PATH. Throughout this manual, we will assume that you have installed Stata
in /usr/local/stata13 and used a symbolic link to /usr/local/stata.
Upgrading
If you are upgrading from Stata 12, you can leave Stata 12 installed where
it is, allowing you to have both Stata 12 and Stata 13. Install Stata 13 in
/usr/local/stata13 and leave Stata 12 alone.
Have your users modify their shell start-up scripts to use the proper PATH for
Stata 13. Otherwise, when they run Stata, they will be running Stata 12.
If you want to uninstall Stata 12, type
# rm -r /usr/local/stata12
to remove it. If Stata 12 is installed in a different directory, you will have
to change the above command accordingly.
Install Stata
Set your current directory to /usr/local/stata13 and run the installation
script,
# cd /usr/local/stata13
# /media/Stata/install
replacing /media/Stata with the path to the installation media if your device
path differs (other common paths are /dev/cdrom and /mount/stata). If you
have trouble running the installer, it could be because your version of Unix
will not, by default, allow you to run applications from a installation media.
Please see page 18 for more help.
Follow the prompts. Nothing will be written until you say it is OK to do so.
Initialize the license
Initialize the license by typing
# cd /usr/local/stata13
# ./stinit
[ IG ] Installing Stata for Unix 15
You will be asked if you accept the software license agreement, which can
be found in the file license.pdf on your installation media. Read and accept
the software license agreement to proceed with the installation.
You will be asked for your serial number, code, and authorization, which are
provided in your License and Activation Key. The code and authorization are
not case sensitive. You will also be asked to specify your name and address
if you have a single-user license, or the institution name and department or
address if you have a multiple-user license. When you invoke Stata in the
future, the license information will be displayed along with the name and
address you enter. This information will also be written in system files that
Stata creates so that, should you ever need to send a file to us, we will know
whom it is from. Whenever you or any of your users calls our technical
support line, we will ask for this information, all of which Stata reports when
it begins execution.
If, for some reason, you need to reinitialize the license for an installed
copy of Stata, you will have to contact Stata Technical Support for special
instructions.
Set the message of the day (optional)
Every time Stata is invoked, the contents of /usr/local/stata13/stata.msg
are displayed. This feature provides a convenient way to communicate with
Stata users if you are administering a large site. As superuser, you may edit
the file or erase it if you wish.
Verify that Stata is working
Now that you have completed the installation process, you should verify that
everything has been installed properly. You must log out as superuser and log
in again as a regular Stata user. The prompts below change to $to indicate
your regular user status.
To use Stata as a user, your path must include the Stata installation directory,
and to run the GUI version, you must be running X Windows. For our quick
test, we are going to be crude. The following will work whether you use sh,
csh,bash, or ksh:
% sh
$ PATH=$PATH:/usr/local/stata
$ export PATH
For Stata(console):
$ stata
16 [ IG ] Installing Stata for Unix
For Stata(GUI):
$ xstata
Stata should launch. Use stata-se or xstata-se if you have Stata/SE, stata-
mp or xstata-mp if you have Stata/MP, and stata-sm or xstata-sm if you
have Small Stata. If Stata does not start properly, see page 18.
Assuming that nothing is wrong, type
. exit
$ exit
The first exit took us out of Stata. The second exit took us out of the sh
that we temporarily invoked.
Modify shell start-up script
Once you have verified that Stata is working, modify your shell start-up
script to include Stata in your path. We will assume that you have created a
symbolic link from /usr/local/stata to your Stata installation directory. If
you did not create the recommended symbolic link, substitute your installation
directory for /usr/local/stata in the paths below.
If you use csh or tcsh, there is a line in your .cshrc file (in your home
directory) that looks like
set path = (/bin /usr/bin /usr/local/bin ~/bin)
Edit the file and add /usr/local/stata to the end of the list:
set path = (/bin /usr/bin /usr/local/bin ~/bin /usr/local/stata)
If you use bash,sh, or ksh, there is a line in your .profile (in your home
directory) that looks like
PATH="/bin:/usr/bin:/usr/local/bin:$HOME/bin"
Edit the file and add /usr/local/stata to the list:
PATH="/bin:/usr/bin:/usr/local/bin:$HOME/bin:/usr/local/stata"
If you are using a symbolic link to your Stata installation directory and you
have included the path to the Stata installation directory, be sure that the
symbolic link appears before the true directory in the path.
Log out and log back in so that the changes you have made will take effect.
Stata should now work from any directory on your computer.
[ IG ] Installing Stata for Unix 17
Update Stata if necessary
StataCorp releases updates to Stata often. These updates may include new
features and bug fixes that can be automatically downloaded and installed by
Stata from the Internet. There may be updates to Stata more recent than the
version of Stata on your installation media. You should check for updates to
Stata before you use it for the first time. You can do this one of two ways:
•Select Help > Check for Updates.
•Enter update query from the command line.
It is also a good idea to periodically check for updates to Stata. See [GSU] 19 Up-
dating and extending Stata—Internet functionality for more information about
updating. If you have trouble connecting to the Internet from Stata, visit
http://www.stata.com/support/faqs/web/ for help.
Starting Stata
With Stata for Unix, you can choose between two user interfaces. The first
option is the graphical user interface, or GUI, which we will refer to as
Stata(GUI). The second option is the nongraphical user interface, which we
will refer to as Stata(console). If instructions apply to either interface, we
will simply refer to Stata.
Upon installation, both interfaces are installed, but only the GUI version can
display graphs. If you use X Windows, you will be able to invoke either
interface, GUI or console, at each session. See [GSU] 2 The Stata user interface
for more information about the Stata user interface.
To start Stata from a Unix prompt, type
•xstata or xstata-se or xstata-mp or xstata-sm to start Stata(GUI), or
•stata or stata-se or stata-mp or stata-sm to start Stata(console).
If you see a message telling you that Stata could not find the license file or
if you receive any other error when you try to start Stata, please see page 18.
Stata(GUI) requires X Windows to run.
Stata(console) has a nongraphical interface; it is run in a terminal window,
and output is displayed on the terminal.
18 [ IG ] Installing Stata for Unix
Exiting Stata
To exit Stata(GUI), select Exit from the File menu or press Ctrl +Q. If you
have made any changes to the data in your dataset, including creating a new
dataset, you will be prompted to save the changes.
If you exit Stata by typing the equivalent exit command, which is the only
way to exit the console version of Stata, you will see the following in the
Results window if you have made changes to your data:
 
no; data in memory would be lost
r(4);
 
If you would like to save your changes in Stata(GUI), you could save the
dataset as you save any other file by using File > Save or Ctrl +S. In either
Stata, you can also save the dataset by typing save filename. You could then
type exit again, and Stata will exit. If you do not wish to save your changes,
you can force Stata to exit without saving the dataset by typing exit, clear.
Troubleshooting Unix installation
If you had trouble with the installation of Stata, it could be because you
have a recent copy of Unix that will not allow you to run applications from
aDVD or USB drive. Type df -l to see what local devices are mounted; one
should look like the Stata installation media. For example, you could see
something like
$ df -l
Filesystem 1K-blocks Used Available Use% Mounted on
/dev/hda6 23054660 5528268 16336380 26% /
/dev/hdc 274158 274158 0 100% /media/Stata
/dev/hdc is the device name, and /media/Stata is the mount point.
If you see something indicating that the Stata installation media is successfully
mounted, you need to see if you are being prevented from running applications
directly from the installation media. Type mount to get information about any
mounted file systems. Somewhere on the list, you should see information
about your installation media. Continuing with the above example, you should
see your device name and mount point in the output:
$ mount
omitted output
/dev/hdc on /media/Stata type iso9660 (ro,noexec,nosuid,nodev,uid=220)
[ IG ] Installing Stata for Unix 19
If you see the term noexec appear, you are not allowed to run applications from
aDVD or USB drive. Your best course of action is to copy everything from
the Stata installation media to a temporary directory and run the installation
from there. Substitute your mount point for /media/Stata below.
$ mkdir /tmp/statainstall
$ cp -r /media/Stata /tmp/statainstall
$ mkdir /usr/local/stata13
$ cd /usr/local/stata13
$ sudo /tmp/statainstall/Stata/install
After you have Stata running and initialized, you can delete the temporary
directory /tmp/statainstall.
If you are still having problems installing or if you have any other troubles,
see the Unix FAQs on our website at http://www.stata.com/support/faqs/unix/.
If this does not help, contact Stata Technical Support. Please gather all the
information you can about your system, including your computer model and
the type and version of Unix that you are using.
Troubleshooting Unix start-up
If you have attempted to invoke Stata(GUI) by typing xstata,xstata-se,
xstata-mp, or xstata-sm at the Unix prompt and it has failed, attempt to
invoke Stata(console) by typing stata,stata-se,stata-mp, or stata-sm at
the Unix prompt. If Stata(console) fails, continue here. If Stata(console) starts
without problems, see the next section of this chapter.
You tried to start Stata and it refused; Stata or your operating system presented
a message explaining that something is wrong. Here are the possibilities:
Cannot find Stata directory
Stata first checks in /usr/local/stata13 and then checks in /usr/local/stata
to find the license file. If Stata does not find the license in either of these
locations, it looks in every directory in the Unix PATH. If you receive this
message, most likely the directory where Stata is installed is not in your
PATH. You need to add this directory to your PATH.
Cannot find license file
This message means just what it says; nothing is too seriously wrong. Stata
simply could not find what it is looking for. The two most common reasons
for this are that you did not complete the installation process or that Stata
is not installed where it should be.
Did you insert the codes on your License and Activation Key to unlock Stata?
If not, go back and complete the initialization procedure.
Assuming that you did unlock Stata, Stata is merely mislocated, or the
location has not been filled in.

Error opening or reading the file
Something is distinctly wrong and for purely technical reasons. Stata found
the file that it was looking for, but either the operating system refused to let
Stata open it or there was an I/O error.
The stata.lic file could have incorrect permissions. Verify that stata.lic is
in /usr/local/stata (or at least in the directory linked to /usr/local/stata)
and that everybody has been granted read permission. To change the permis-
sions, become superuser by logging in as root (using su or sudo) and type
chmod a+r /usr/local/stata13/stata.lic.
Other messages
The other messages indicate that Stata thinks you are attempting to do
something that you are not licensed to do. Most commonly, you are attempting
to run Stata over a network when you do not have a network license, but there
are many other alternatives. There are two possibilities: either you really are
attempting to do something that you are not licensed to do, or Stata is wrong.
In either case, you are going to have to contact us. Your license can be
upgraded, or, if Stata is wrong, we can provide codes to make Stata stop
thinking that you are violating the license; see [U] 3.9 Technical support.
Stata(console) starts but Stata(GUI) does not
Trouble with libraries
Stata, like many other programs designed for Unix machines, needs certain
system libraries to run. Most of the standard library routines that Stata
needs are included in the Stata binary. However, Stata does rely on a few
external libraries. For example, Stata assumes that your system will have
the standard C library available. Stata(GUI) assumes that you have the X
Windows libraries as well. These libraries are often located in different places
on different implementations of Unix. For example, under Linux, the standard
C libraries can be found in /lib, whereas the X Windows libraries are in
/usr/lib; under Solaris, both the standard libraries and the X libraries are
in /usr/lib. The operating system needs to know where to find the libraries
that Stata needs to run. The Unix environment variable LD LIBRARY PATH
tells the operating system where to find libraries. If you get an error message
that says something like
ld.so.1: xstata: fatal: some library.so.#: can’t open file
the likely reason is that the operating system cannot find the necessary
libraries. Stata does not rely on any unique libraries; you can rest assured
that the libraries you need are on your system. You should look for the
library in question on your system and make sure the environment variable
LD LIBRARY PATH includes the path to the directory where the library in
question is located. Your system administrator may be able to help with this
task.

Setting the DISPLAY environment variable
Sometimes when executing Stata in a networked environment, Stata(GUI) will
produce the error message
You need X Windows for this version of Stata.
This means that Stata has not found the DISPLAY environment variable. You
need to set the DISPLAY variable to be the screen on which you want Stata(GUI)
to appear. For example, in csh, type setenv DISPLAY machine:0.0.
xhost permissions
Another related error message can occur with Stata(GUI). When Stata is being
run in a networked environment, the computer on which Stata(GUI) is actually
executing may not have permission to draw on the screen of the computer
on which you have asked Stata to draw. Then you may see the following:
Xlib: connection to machine name:0.0 refused by server
Xlib: Client is not authorized to connect to Server
xhost: unable to open display
This means that the machine that is actually executing the Stata instructions
(the x-client in X Windows parlance) does not have permission to draw on
the screen of the computer that you have asked it to (the x-server). On the
machine on which you want to display Stata(GUI), type
% xhost +client machine
This will give the client permission to draw on the server.

Documentation
All the documentation for Stata is included in PDF format. You can open
it from within Stata by clicking on Help > PDF Documentation. It is also
linked into Stata’s system help. If you want to get to the PDF documents
directly, they can be found in the docs subdirectory of the Stata instal-
lation directory. There is also a copy of the manuals at the top level
of the installation installation media. For information about how to opti-
mally set up Adobe Reader for viewing the PDF manuals, please visit
http://www.stata.com/support/faqs/res/documentation.html.
When reading the manuals, you will find references to other Stata manuals.
For example,
[U] 26 Overview of Stata estimation commands
[R]regress
The first example is a reference to chapter 26, Overview of Stata estima-
tion commands, in the User’s Guide; and the second is a reference to the
regress entry in the Base Reference Manual. All of these are clickable in the
PDF documentation.
