Hello,
FYI, there may be a bug in version 4.0.16 (free) because during a repair the system hangs in this section:
08 - Repair MDAC/MS Jet
Start (4/7/2018 9:52:07 PM)
Running Repair Under Current User Account
Running Repair Under System Account
Done (4/8/2018 7:46:06 PM)
Once I close that window the repair continues but this issue has happened twice in a row and I thought you would like to know.
