Has anyone been able to develop a VB 6.0 database (Jet 4.0 / MDB file) application under XP and distribute it to Windows 98 machines? I can develop in XP/2000/98 and the application runs, but if the application is packaged under XP - you are never prompted to include the MDAC. This is not the case under 98/2000 - SAME APP NO CHANGES. The Windows XP compile, if installed to a 98 machine changes something that makes the computer nonbootable on next start. The same app compiled and packaged under Windows 98 installs without error. What gives - is VB not able to retro compile?
