When replacing an expired license file, how do I clear the FlexLM licensing environment variable in Windows registry?
The Flexlm license is a third party tool. It modifies Windows' registry and system environment variable LM_LICENSE_FILE. During installation, it will not delete the old paths in registry, thus sometimes it may still point to the incorrect file when there are multiple license files exist. This can become an issue causing the software using the old license instead of the new one. Flexlm License file variable is stored in PC registry. When ispLEVER software is being installed, it will add a path in the LM_LICENSE_FILE(environment variable). When it is uninstalled, the path can't be deleted automatically.
Here is the procedure to clean the registry:
1. Close all Lattice Software Tool.
2. Windows menu Start-Run-regedit (to bring up Windows Registry)
3. Search for the environment variables "LM_LICENSE_FILE" and "LATTICE_LICENSE_FILE".
4. Replace the value of all "LATTICE_LICENSE_FILE" and "LM_LICENSE_FILE" with the correct license path.
5. This should help you open the Lattice Software Tool.
