Windows 7 64 bit supports to run both 64 bit and 32 bit applications - even though they use a completely different instruction set. So in principle, 32 bit applications continue to run.However, Windows does not support loading 32 bit DLL's into a 64 bit process, or vice versa.Jet 4 continues to be available as 32 bit DLL's, thus, 32 bit processes can continue to make use of it. Eryang's comment merely means there are no 64 bit binaries of the Jet4 drivers (as of timeposting), thus 64 bit processes are not supported.

Running on a 64-bit machine will default to a 64-bit web application pool and it will not be able to find the 32-bit version of the Jet engine component.The solution is to configure the application pool and enable 32-bit application support. For IIS 7, running on Windows Vista, you can do this from the application pool's advanced settings dialog:You can do the same for Windows 2003 and IIS 6 by following the instructions in.
