I guess they made 64bit wrapper/shim DLLs around 32bit JET, I can be
wrong...

BTW, I have got already met with that issue - one of my customers did
purchase 64bit PC, and they use .NET programs with MS Access backends -
solution for .NET is to use CorFlags.exe from .NET/Windows SDK to set .NET
app running in 32bit mode then it will use 32bit JET DLLs on 64bit system...

...anyone with more info on this? ...how can they release a 64 bit Access 
2010 w/o a corresponding 64 bit Jet engine?
...the ocx issues would be small potatoes compared to this.
