The actual name of the directory used to store our vendor daemon (if it ends with numinno) can cause some locking. For example if you were to install flexlm in the directory below will cause locking:
c:\FLEXnet\numinno
Changing the installation directory name to c:\FLEXnet, or c:\flexlm\numinno_fab3000, or any directory path that does not end in "numinno" fixes the problem.
