MMC: Error Adding Enterprise Server for .NET Snap-in

An error occurs when trying to add the SEE Administration snap-in to the MMC.

Possible causes

The SEE Administration snap-in requires .NET framework 4.0 to run and MMC is running with an earlier framework version.

To resolve this, in the environment space used by the MMC, set the COMPLUS_Version environment variable to v4.0.30319. For example, in the command window before you run mmc.exe, use the following command:

set COMPLUS_Version=v4.0.30319
