MMC cannot open the file C:\WINDOWS\system32\gpmc.msc

Today I have got the below error when I try open Group Policy Management Console by running the command the gpmc.msc. I’ve been using it for long time, it is not working only now.

MMC cannot open the file C:\WINDOWS\system32\gpmc.msc.This may be because the file does not exist, is not an MMC console, or was created by a later version of MMC. This may also be because you do not have sufficient access rights to the file."

Fix/Solution for MMC cannot open the file gpmc.msc

After I have analyzed some time, found the reason for the error is the gpmc template file is corrupted under user’s appdata location: %APPDATA%MicrosoftMMC

To fix this issue, we need to correct the corrupted gpmc template file, but this would be hard task, don’t worry you can just rename the corrupted template file and it will automatically created when you open Group Policy Management Console by running the command the gpmc.msc.

1. Open the Run command window, type the path %APPDATA%MicrosoftMMC and click OK.

MMC cannot open the file C:WINDOWSsystem32gpmc.msc

2. Rename the corrupted gpmc template file into gpmc-backup. Now you can open Group Policy Management Console by running the command the gpmc.msc.

  1. didn’t do anything, windows cannot find %APPDATA%MicrosoftMMC. been trying to turn on my windows defender for three weeks, all the pathways to fix it end in “windows can’t find it” or “you do not have permission”, nothing ever works.
