Dongle not connected error on Windows 2012 R2 OS

Hello,

I am using Aladin dongle with ID-9-00670714. On Windows Server 2012 R2 OS, I am getting error like "Dongle not connected" while stating lmgrd.exe as windows service.
The same dongle works fine on Windows 7 and Windows 2008 Server operating systems.
Any idea why it is not working on Windows 2012 R2 system?
