I have an AutoCAD ObjectARX (C++) and .NET (C#) application that connects to both Access via the JET engine and VFP databases via the VFP OLEDB driver (vfpoledb.1). In 64bit Windows there is now a 64bit Access driver available so I just need to modify the C++ code to use that driver instead of the old one, a simple change to a connection string. The problem is that there is no such 64bit driver available for FoxPro. Microsoft's "solution" is 'run it in 32bit mode', see Ximy's reply at http://social.msdn.microsoft.com/forums/en-US/adodotnetdataproviders/thread/6bcde49e-1532-4e87-aef3-ee24cbc18225, Cindy Winegarden's reply at http://www.vistax64.com/vista-general/22170-odbc-vista-foxpro.html and Cetin's reply at http://social.msdn.microsoft.com/Forums/en-US/visualfoxprogeneral/thread/272f47cf-a02a-4aa4-b4e5-a345921b9553 ("You can't access VFP data over VFPOLEDB using 64 bits calls. However, you can use VFPOLEDB in 64 bits OS (provided calling party is not 64)")

Unfortunately this doesn't work for AutoCAD addins since 32bit AutoCAD cannot run on 64bit Windows, my AutoCAD addin MUST be a 64bit process.
Can anyone suggest a solution?
