Excel97 crash, Windows 7, VBA, DEP

I've not be able to get Excel 97 VBA to run correctly on Win 7 without
turning DEP entirely off. Access97 runs ok with just an Access DEP
exception, But making Excel a DEP exception has not helped.
Specifically, Excel 97 crashes and closes when I (a) try to delete an
add-in, or (b) call a Win32 API (even after I remove all the add-ins), or
(c) use a Forms button (which is a call to a COM object).
I can (and have) remove all the add-ins by moving the files. I can (and
have) remove all the unused references, including forms2.
Can you suggest any other DEP exclusions that might make Excel happy?
