Microsoft's latest Compatibility Update (Dec 2001) covers Approach v9.1, 9.5 and 9.6.
v9.7 was XP certified at release anyway.
When install v9.7 on Windows XP you get a message stating that there are problems with running Approach on Windows XP. Actually, v9.7 works perfectly fine on XP. Other v9.*'s also run fine except that printing crosstabs doesn't work. (Note: Printing crosstabs from any version before v9.7 doesn't work on any edition Windows, so if this hasn't been a problem for you in the past then it obviously isn't a feature you use anyway!)
16 bit applications such as v3.0* and earlier won't run under XP
