No, most clients will only buy 1 or may be 2 dvd. That data is different research results for different counties in Texas. Each dvd will have 1 or 2 counties on it, depending on the size of the data for that county. The app will run on the dvd and will not need to be installed. (it is a simple vb exe file) What I'm trying to figure out is if MSDE will run from a DVD, and if it can, how and what do I need to install for it to work? (I know some item will need to be installed for this app to work)
