IMAT licenses are supplied by the Sentinel RMS server, which is provided as a separate installation. This version of IMAT requires Sentinel RMS 9.1 or newer. You can download the latest version of the license server by clicking here.

Please follow the installation instructions that come with the server package to install and configure the license server.  You will need to contact ATA Engineering for a license file. Assuming this is installed and configured correctly, all you need to do for IMAT is to set the environment variable LSHOST to point to the server.  On Linux/Unix, you can set this variable using the command

export LSHOST=no-net~server
setenv LSHOST=no-net~server      ( C shell )

On Windows, you can define it in Settings | Control Panel | System.

Alternatively, you can set the environment variable LSFORCEHOST to the name of your license server. This is necessary if your license server is on a different subnet, and it should speed up initial license checkout slightly.
