I dropped an Access97 stand alone program onto a computer that has access2000 already on it. The program runs fine. But when they open up a different database in Access2000 that database in 2000 no longer works. If I go in and run the Msaccess.exe in 2000 it will work again. But, now if I run the 97 stand alone, it will not run and asks to be converted to 2000 which an .mde file can't do. Any ideas?
