Description

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

Comments

The error may indicate that DeviceLock Management Console snap-in was not installed correctly or that DLMgmt.dll file is either missing, or corrupted.

Recommendations

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.dllregsvr32 DLMgmt_x64.dll

Do the same for DLMgmt.dll:regsvr32 /u DLMgmt.dllregsvr32 DLMgmt.dll
