Seemage cannot be connected to the server

Question: During the launch of Seemage applications (nodelock or floating licenses), the display of the machine shows a warning indicating that Seemage cannot be connected to the server. What should I do?
Answer: It happens from time to time. This problem is linked to the FLEXlm software, and the way the variable LM_LICENSE_FILE is initialized. There is a way to go around the problem. Put the DWORD UseVariable in HKEY_LOCAL_MACHINE\SOFTWARE\Seemage\LicenseManager DWORD has two values: 0 and 1(by default). You will need to modify it to 0, if the Seemage applications are not launched. Please note that you will need the administrator mode to write into HKEY_MACHINE_LOCAL.
