Where is the license file on a network license server?

The license file is normally stored in the network license manager installation folder, on Windows this usually is: C:\Program Files\Bricsys\Bricsys Network License Manager.

The license file is named Bricsys.lic by default.

If multiple license keys are activated on the server, these are stored in different license files by default. They are called Bricsys.lic, Bricsys2.lic etc.
