As far as I know the main compatibility issues relate to non-Office OCX
controls and API calls. If you use either of these features in a 32-bit
version then you might have problems running those workbooks in 64-bit.

As far as I know, if a workbook works in 64-bit it should also work in
32-bit but I don't have a 64-bit machine myself so I am not speaking from
experience.

Thank you Bill, this confirms my assumptions. I think that also the add-ins
need to be recompiled in 64 bit Visual Studio as well.

COM add-ins - I believe you are correct.

I've been using the Microsoft Office 2010 Beta and so far, I've had absolutely no problems when it came to backwards compatibility. Files created in 2010 were perfect utilized in 2007 and so on. I'm actually very surprised because that is always a program's biggest flaw. Adobe is really bad about not making things backwards compatible -- especially with large projects. Yikes!
