MMC cannot open the file C:\WINNT\system32\*.msc

[[email protected]]

After uninstalling AverMedia's AverTV, I could not open any *.msc
(Microsoft Management Console) files, such as Event Viewer, Computer
Management, Device Management, and etcetra.

This resolved it

regsvr32 C:\Windows\system32\msxml3.dll
