MMC cannot create the snap-in because of current user policy

[Wendy7390]

I was getting this error when after installing Endpoint Encryption 11.2 on a brand new server.  I got the error on the Software Setup and the Management password.

The problem is with Microsoft Management Console and requires a registry fix.

Make sure you export your registry before trying the following:

MMC Cannot create the snap-in because of current user policies.

         

1.         Start Registry Editor (regedit.exe).

2.         Move to HKEY_CURRENT_USER\Software\Policies\Microsoft\MMC

3.         Open the CLSID number giving the error

4  .      Double click RestrictToPermittedSnapins or something close to this

5.         Set to 0 and click OK

6.         Close the registry editor

This is not something I've ever encountered myself.  Do you have anymore details so that we know what to look out for?

What was the OS?  What kind of GPOs do you have applied (as it does sound like a GPO restriction of some sort)?
