Have a client that has a fairly important Win7 Pro workstation with this problem. Also cannot get IIS Manager to launch (does nothing). Hence, I wanted to check the Event Viewer to track down the issue. Got the screen below.
Have tried several things, referenced here:
http://answers.microsoft.com/en-us/windows/forum/windows_7-performance/event-viewer-mmc-could-not-cr...
 including exporting and deleting the referenced SnapIN CLSID key in the registry. SFC /Scanow, etc. But not getting anywhere thus far. Really do not want to re-image or reinstall if it can be avoided.
Anyone run into this?Screen shot

Update: I have found that the same MMC problem occurs with Task Scheduler. But most of the SnapIns, including Services, run OK. Also, other key programs on the workstation are still functioning.

Can you confirm you have .Net framework installed? If not go here https://www.microsoft.com/net/core#windows download NET Core 1.0.1 - VS 2015 Tooling Preview 2 and try again.

Yes, .NET 3.5 s in installed. I have tried to the trick suggested of enabling & disabling it in Windows features.  Also, I tried the fix of renaming  the file %SystemRoot%\Microsoft.NET\Framework64\v2.0.50727\CONFIG\machine.config.

Nothing has worked thus far.

You’ve updated all your end user’s email signatures. Hooray! But guess what? They’re playing around with the HTML, adding stupid taglines and ruining the imagery. Find out how you can save your signatures from end users today.

1) Did you try deleting all configuration files under %userprofile%\Application Data\Microsoft\MMC and restarting Event viewer and Task Scheduler?

2) Please navigate to the following registry:

HKEY_LOCAL_MACHINE \ SOFTWARE \ Microsoft \
MMC \ SnapIns \  wert.PNG
 export the above registry (as a backup), then delete it.

3) also try this:

Thanks for the post, Hopeleonie. I dd try tot delete the entire HKEY_LOCAL_MACHINE \ SOFTWARE \ Microsoft \
MMC \ SnapIns \   registry section, but I did already delete the the CLSID: FX:{ ... }  keys that were related to the Event Viewer and Task Mgr (as referenced in the link provided).  This had no effect. After rebooting the keys were not automatically recreated.
