Hi,

I have a problem: MMC could not create snap-in

MMC.exe is ok, but i can't add these snap-ins:

Event viewer, Internet Information Services (IIS) Manager, Local Backup, Nap Client Configuration, Resultant Set of Policy, Task Scheduler, TPM Management, Windows Firewall with Advanced Security, Windows Server Backup

.net has been reinstalled. (The removal caused a big problem. e.g Visual Studio; This has been resolved.)

I've read similar posts but I'm not sure what I should do.

Thank you!

Hi,

Check the state of .NET. Reference link below for more information about .NET Framework Setup Verification Tool User's Guide:

Besides, run SFC /ACANNOW or DISM.exe to check the system files:
