Configuration Manager Console fails to open with the following error: “MMC cannot initialize the snap-in.”
After clicking on OK, empty Configuration Manager Console opens as shown on the screenshot below:
Open new instance of the Microsoft Management Console (MMC) (Start -> Run… -> mmc -> OK) and go to File -> Options -> Disk Cleanup.
Click on the Delete Files to delete MMC cache files and per-user preferences for console files which are saved in user’s profile.
After that, restart Configuration Manager Console to verify if it now works as expected.
