Hi @Pankaj G,

If your colleague is able to properly get a license from your license server, that suggests that your license server is configured and working properly.

You should compare your client software licensing settings with your colleague's to make sure that the port and servername/IP address are entered correctly. Also, make sure that the box for "use concurrent licensing" is checked:

Some other things to check:

• If your license server is hosting an older version of the license than the software you have installed, you will either need to install that older version of the software to match the license, or if your maintenance is current you could upgrade the license on your license server for use with the latest version of FlexSim.
• If you are starting FlexSim but all other seats are currently in use by other users, you will not be able to get a license until one of them closes FlexSim.
• Your specific computer could have firewall or other connectivity issues blocking your client software's communication with the license server. There is a ping test and telnet test you can use to check described in 10. Troubleshooting client-server licensing problems on page 21 of our license server installation instructions.
• In addition to the above there are more troubleshooting suggestions in the license server installation instructions.

If you're still not able to get your licensing working, please contact your local FlexSim representative directly via phone or email for live support, or to schedule a web meeting where we could look at your client software (and possibly your license server) to troubleshoot with you.
