FOUD WORKAROUND!:

And it works for me
Essence is to replace ONLY the MSJET40.DLL file with an older verion.
Windows System File protection protects the msjet40.dll file when you try to replace it with an older version. How to fix this issue:
1. Disable system file protection (not verry neat) or...
2. Make sure systemfile protection uses the old MSJET40.dll file
option 2 is preferable to me. I'll explain how:
1. Go to %SystemRoot%\system32\dllcache (it is a hidden system folder) and replace MSJET40.dll with the old version (4.0.8618.0)
2. Go to %SystemRoot%\system32 and also replace the MSJET40.dll file.
This must be done in the specified order.
Now SFP thinks the file is correct and will not replace it.
Access works again! Happy days are there again.
