Do you mean "run Approach executable" on Vista, or transfer the database to another application?
Approach is compatible with Vista 32-bit editions, according to IBM, but not with Vista SP1.
Interestingly, it also has problems with XP SP3.
If you can export the database in a common format (delimited text file of some sort), I'm sure you could pull it (the data) into Access or similar.
Assumes you can find a PC to run Approach on, though!
