Problem
Start Flexlm license manager by clicking "Start" button few times but the prompt "License....can not start" is still there. Closed license manager, then re-open it, the License manager is running some how, button "Stop" appear.
From task manager, I see the process "LMGRD.exe"(Service of license manager) is running. After waiting for a moment, INTEL.exe just start/stop (appeared / deleted) rapidly. After a little more, LMGRD.exe is disappeared too.
From license server log, found below error message after license manager started:
11:35:36 (lmgrd) Starting vendor daemons ...
11:35:36 (lmgrd) License server manager (lmgrd) startup failed:

Version
Windows 7
FlexNet Licensing v11.12.0.0
Solution
1. Stop the license service using LMTOOLS.EXE or in Windows Services.
2. Stop any process in Task Manager like lmgrd.exe and adskflex.exe (or whatever the vendor daemon is named).
3. Start the DEP program from Control Panel > System > Advanced > Performance Settings > Data Excution Prevention.
4. Add an exception for LMGRD.exe, INTEL.exe and possibly also LMUTIL.EXE, LMTOOLS.EXE where the license manager is installed. Or you may select turn off DEP for all programs.
