I'm new to creating actual packages for deployment, since I generally have full control of the machines I deploy to, and so I usually copy & register any needed libraries manually. (I know, bad idea) However, this time I need a package, since we're actually talking about distributing this one to clients.

The machines I'm deploying to (at least the first ones) are locked down pretty tight, so apps (and, in particular, library files in the system directory) can only be installed under an admin login.

I've created installs using both the P&D wizard and Inno, and in both cases it seems to install ok, and runs ok when I'm still logged in as the admin, but when the admin logs off and the actual user logs back in, I get "Unexpected Error; Quitting" when I try to run my app.

My app includes a couple of custom library files, a bunch of IPWorks libraries, and a handful of other libraries, so I don't know if any of those might be causing the problem, or if it's something else.

Any ideas?
