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.
