Hello @AlexBlanes-8504,

Thank you for reaching out to the Microsoft Q&A platform. Happy to answer your question.

This problem could occur if the snap-in’s registry configuration is broken or if the system files are corrupt. Have you done any recent windows updates on this machine? If not you can try to patch this machine up with all the latest available windows updates.
Also, We can try to fix this issue by using below methods. Perform the methods until the issue is fixed.

Fix 1 – Fix the Registry
As registry configuration error can cause this error as well, we will try to fix the registry. Follow the steps to perform this method.

Note: – Before doing anything with registry editor first of all create a registry backup, so that if anything unexpected happens, you can just import the backed up registry file and make everything normal again.

Step 1. Open Run. To open Run, right-click on the Start menu button and select Run, type regedit and launch the registry editor
Step 2. On the left side of the window, follow the following path.HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\MMC\SnapIns

Step 3. Double click on the SnapIns folder to expand it. Now, in the Snapins folder, look for the folder whose name was specified in the error message as CLSID or FX ID.

Step 4. After finding the correct folder, right-click on the same folder and select Delete.
When asked for confirmation, click on Yes.
Step 5. Now, Restart your computer.

Fix 2 – Rename mmc.exe
1. Open file explorer and browse to the following location:-

C:\Windows\System32
2. Now, rename mmc.exe to mmc.exe.backup
Now, try again and see if the issue gets resolved or not.

If above 2 fixes are of no help, Turn On .NET Framework on this machine. Turning on Microsoft .NET Framework has worked for most of the users with this issue.

Please "Accept as Answer" and Upvote if any of the above helped to help others in the community looking for remediation for similar issues.
