Hi Carl,

>Install Shield Express lets you have a "Database Folder" dialog. Once the app is installed, how does it know what dir the user specified?

You can set InstallShield Express to create registry entry and use Windows Installer property '[DATABASEDIR]' as a registry key value.

>Also, it defaults to "c:\program files\MyApp\" which is bad. On NT (2k/xp) the users don't have write rights to that. I would think it should be under "\documents and settings\all users\application data\MyApp" right?

No, default is '[INSTALLDIR]\Database' but you can choose anything else from the dropdown list in General Information -> DATABASEDIR.
