Citrix: Citrix XenApp 6 and IMA Service won’t start

I recently build a Citrix XenApp 6 deployment using RES Automation Manager but encountered problems with some (not all) installations. After a default installation the IMA service couldn’t start.  When looking at the eventlogs of one of those specific servers I found the following errors:

Failed to load plugin C:\Program Files (x86)\Citrix\System32\Citrix\IMA\SubSystems\ImaAppSs.dll with error IMA_RESULT_WRITE_TO_LOG_FAILED

Failed to load initial plugins with error IMA_RESULT_WRITE_TO_LOG_FAILED

and further on in the eventlog the following error was presented:

When searching on the internet I found the following fix:

Well apparently this is a Citrix common item because the Citrix tech went straight to this registry key and changed it.

Then blanked out the following keys:

After that, IMA magically starts and all services come back up and running.

So based on this I took one of the XenApp 6 servers and blanked those keys:

After this I could start the IMA service again and I was able to launch a published desktop on this server again.

    I received this error, and nothing as above and other forums solved my issue. I found the solution as below:
    Error: The Citrix Independent Management Architecture service terminated with service-specific error %%-2147483601. And also Citrix MFCom service was in starting mode.
    à NTFS permissions on file C:\Windows\SysWOW64\mscoree.dll reset to default: SYSTEM, Administrators, Users: Read and Read & Execute
    NT Service\TrustedInstaller: Full Control
