Can not open Forticlient console on windows 2012

[ArifS]

I upgraded Forticlient from 7.0 to 7.2.2 on our servers and found that only on windows 2012 servers, I can't start Forticlient console. It gives following error when try open. I wanted to try uninstall and reinstall but to uninstall Forticlient I have to disconnect telemetry from the console. Is there any solution to fix issue. 

"the procedure entry point DiscardVirtualMemory could not be located in the dynamic link library in C:\Program Files\Fortinet\FortiClient".

Hello Dear ArifS,

You can disconnect FortiClient from the command prompt window with FortiESNAC.exe CLI commands.

Run the "cmd.exe"

Navigate the path:
cd c:\Program Files\Fortinet\FortiClient\

Then run the unregister command.

FortiESNAC.exe -u

If you have a de-register password assigned in system settings profile, use the following command

FortiESNAC.exe -u -k PASSWORD_HERE

FortiESNAC CLI commands

Hi Aliyavuzer

I uninstalled manually and reinstalled FortiClient with luck. Still gives the same error when try to open console.

Hello @ArifS ,
I skipped the OS Version, sorry about that. 

Windows Server 2012 is no longer supported on Forticlient GA versions released recently.

System requirements Forticlient v7.2.2 
System requirements Forticlient v7.0.10
