Sometimes users are running applications that are older than you would like or maybe you're just curious. Either way, you can gain insight into the application versions users are running by looking at the usage status of your license server with lmstat. The lmstat command shows not only the version of the license checked out but the version of the license the application requested. The requested version can be used to find who is running older versions. For example:
$ lmutil lmstat -f msimviewer -c 1717@server

The license version (aka Exact Access Date or EAD), made bold for the example, usually corresponds to the release date of the application but you can check the application's release notes on SupportNet for confirmation. Better yet, find the user running the application and confirm the version they're running. You may want to point them to the latest release.
