Hi,

Were getting the same problem, and it looks like its either Windows update or Kaspersky AV that caused the problem. Was able to fix it by getting a copy of System.mdw (should be installed by access) then copying it to the users ...\System32 directory. Once you have done that amend the HKLM\Software\Microsoft\Jet\4.0\Engines\SystemDB key in the registry so it contains the full path (including filename) of the System.mdw file you placed in system32.

Regards
