Installation Guide for Windows

Running Multiple Versions of MATLAB

You can run multiple versions of MATLAB on the same system without any special considerations in stand-alone, individual license configurations. In remote access configurations, described in Network Configuration Options, you must perform some additional set up on your license server and possibly on client systems to provide users with access to multiple versions of MATLAB over the network.

Required Setup on Your License Server

To make multiple versions of MATLAB available in a remote access configuration, follow this procedure on your license server:

1. Check the version of your currently installed MATLAB. You must be running MATLAB Version 5.2.x or later to be able to run multiple versions.

2. Stop the license manager. (See .)

3. Remove the license manager service. (See FLEXnet License Management Utilities.)

4. Install the license manager included with the current version of MATLAB on your license server. Run the installer and select the license manager in the product list. (See Step 7: Specify Installation Folder.)

Required Setup on Client Systems

You must make sure that client installations of MATLAB use the latest version of the license manager.

On Windows systems, the License File in a client installation typically includes a SERVER line and a USE_SERVER line, as follows.

SERVER my_server INTERNET=144.212.121.14 27000 
USE_SERVER

If your SERVER line still identifies the correct license server, you do not need to make any changes to your License File.

In heterogeneous configurations that include clients running on UNIX systems, or if you changed which system is your license server, you must replace the License File in client installations with the License File created by the installer during the license manager installation on your license server. On license servers, the License File resides in the matlabroot\flexlm folder. The following table lists the location of the License File on client systems for different MATLAB releases.
