-96 License server machine is down or not responding.
See the system administrator about starting the server,
or make sure that you're referring to the right host

rgruychev ,


It looks like the license manager is either not running on your machine, or you are possibly experiencing firewall blockage. I would open LMTOOLS and perform a “Status Enquiry” to ensure your services are both running and you have license available. If you do, drop your firewall and see if it helps.

If you have seats, drop the firewall, and still cannot pull a seat, you need to make sure your machines are looking to the correct server for a seat. You can force a direction with a license variable.

1.)           Right-click the My Computer icon.

2.)           Click the Advanced tab.

3.)           Click "Environment Variables".

4.)           Under the System Variables window, click "New".

5.)           In the Variable name field enter ADSKFLEX_LICENSE_FILE

6.)           In the Variable value field enter @YOUR_SERVER_IP_ADDRESS

7.)           Click "Okay".
