Microsoft Access MDAC detect and install...

I need my script to check for Data Access Objects because my program uses jet to access an Access 97 database. The install works fine on my computer but when I run it on a testbed computer it fails unless I install MDAC. How can I check for this and install it during install if it is needed. Keep in mind the Windows 9xME uses one version and 2K/NT/XP/Vista uses another further complicating things.
Thanks very much if you can help me figure this out!!!

My program is at versehelper.tripod.com for now.
