Resolving "MMC could not create the snap-in" error in DeviceLock Management Console


Using DeviceLock Management Console is not possible due to the "MMC could not create the snap-in" error in the right pane.


The error may indicate that DeviceLock Management Console snap-in was notinstalled correctly or that DLMgmt.dll file is either missing, or corrupted.


1. Reinstall DeviceLock Consoles using the "setup.exe" installer with option "Everyone on this computer" (existed in old version installers).

2. Make sure that DLMgmt.dll/DLMgmt_x64.dll file is present in DeviceLock installation folder ("C:\Program Files\DeviceLock" by default);

3. Try to RE-register both 64-bit and 32-bit .dll files,i.e. execute the following command as Administrator:

regsvr32 /u DLMgmt_x64.dll
regsvr32 DLMgmt_x64.dll

Do the same for DLMgmt.dll:

regsvr32 /u DLMgmt.dll
regsvr32 DLMgmt.dll
