A further update on my troubles with InstallShield Developer (both 7.03 and 8). Jerome at InstallShield tech just got me past a very frustrating bug. My Visual FoxPro .EXE files would not get overwritten on patches or minor upgrades. The solution was right click on each key file under Components - Files, uncheck Use System Attributes, and type in the file version and size myself. I don't know why it's needed, but it works great.
