error when installing opsmgr

less than 1 minute read

Yesterday I wanted to install my second management server on a windows 2003 R2 SP2 machine. I installed all the requirements and ran the prerequisite checker.



I was really astonished! It was the first time I saw this error and didn’t understand it!




This problem occurs if the primary interoperability assembly ( is no longer registered in the global assembly cache after you install Microsoft Windows Server 2003 with Service Pack 1 or Windows Server 2003 with Service Pack 2.

To resolve this problem in Windows Server 2003 with Service Pack 2, re-register the primary interoperability assembly in the global assembly cache.
To do this, follow these steps:

  1. Click Start, click Run, type cmd , and then click OK.
    • At the command prompt, type the following commands. Press ENTER after you type each command.
    • cd %windir%Microsoft.NETAuthMan1.2
      • azrlreg register</ul>
      • run the prerequisite checker again and everything is green now!</ol>
