Running the Mathsoft service from lmtools.exe yields the following error message:

Cannot open lock file ((null)): Permission denied
MULTIPLE "mathsoft" servers running.
Please kill, and run lmreread

This error probably results from either:

1. Another copy of lmgrd running
2. A prior lmgrd was killed with "kill -9" (which would leave the vendor daemon running). To correct this, do a "ps -ax | grep mathsoft" (or equivalent "ps" command) and kill the "mathsoft" process

Cause: When the license daemon (lmgrd) is started, it creates a temporary file called "mathsoft" in the folder c:\FLEXlm (this is a FLEXlm default). Thus, installing the FLEXlm program files to a folder called C:\FLEXlm\Mathsoft, rather than the default location, C:\Program Files\MathSoft\FLEXlm prevents the creation of the necessary "mathsoft" file. In turn, the mathsoft.exe process is not started.

Solution: Avoid having a folder named mathsoft in the location c:\FLEXlm. You should also ensure that you have a C:\FLEXlm folder.
