I incorrectly used the web feedback form to send the following text originally,  however, I have since resolved the issue. The solution is to install the missing dll’s which can be packaged as a redistributable.  MSAccess 2003 becomes stable and QODBC actually becomes faster in returning data.

Original communication:
I am testing the QODBC driver with Quickbooks 2007 Premier and Microsoft Access 2003 on Windows XP SP2. When I run a passthrough query multiple times, the Access database crashes. In the event viewer I see the following in Application events:

Faulting application msaccess.exe, version 11.0.6566.0, stamp 42cdb33e, faulting module msjet40.dll, version 4.0.8618.0, stamp 403430ac, debug? 0, fault address 0x00044854.

I see the following three events in System events:

1. Dependent Assembly Microsoft.VC80.MFCLOC could not be found and Last Error was The referenced assembly is not installed on your system.
2. Resolve Partial Assembly failed for Microsoft.VC80.MFCLOC. Reference error message: The referenced assembly is not installed on your system.
3. Dependent Assembly Microsoft.VC80.MFCLOC could not be found and Last Error was The referenced assembly is not installed on your system. 

MFC80.DLL is a part of the Microsoft Foundation Classes and is normally deployed as redistributable components in Visual Studio and Visual C++ dynamically linked applications and is not a part of QODBC.
