Windows Server 2008R2 – mmc cannot open the file c:\windows\system32\servermanager.msc

If you have a problem with mmc cannot open the file like the screenshot above, you can do the following task :

You can try go to this path “C:\Users\%username%\AppData\Roaming\Microsoft” on a Windows 2008 R2 server, deleting or rename MMC folder and check the result. I hope this solved your problem 🙂
