Go to Start | Search| For Files or Folders andsearch for the MSMASK32.ocx file in your Windows/System32 directory.
If you do not locate this file, copy it over from a working workstation and paste it into the Windows/System32 directory on the workstation with the error. Make sure to register the file by opening it with the Regsrv32.exe file located in your Windows/System32 directory.
If the issue still persists, check for Errors in Event Viewer
