Installation Guide for Windows

Running Multiple Versions of MATLAB

You can run multiple stand-alone installations of MATLAB on the same system without any special considerations. Running multiple versions of MATLAB on a license server, however, requires some additional configuration.

If you want to continue running a previously installed version of MATLAB after you install MATLAB 7, note the following:

• The previously installed version of MATLAB must be 5.2.x or higher.
• Both versions of MATLAB must use the latest version of the license manager (FLEXlm). MATLAB 7 requires FLEXlm 9.2.
• The existing MATLAB installation must use the License File created during the installation of MATLAB 7, not the License File created during the original installation.

To set up this configuration, follow these instructions. After completing this procedure, you can start either version of MATLAB that you have installed on your system.

1. Shut down your previously installed version of MATLAB.
2. Stop the license manager. (See Starting and Stopping the License Manager.)
3. Remove the license manager service. (See Removing the License Manager Service.)
4. Install MATLAB 7 on your client systems. (See Installing MATLAB on a Client System.)
5. Replace the License File used by your existing MATLAB installation with the License File created by the installer during the new installation. This table lists the location of the License File on client systems for different MATLAB releases.
   
   

   MATLAB Version	Location of License File on Client Systems
   MATLAB 6.x	$MATLAB\bin\win32\license.dat
   MATLAB 5.2.x or 5.3.x	$MATLAB\bin\license.dat
