Deploying Applications Help

I have successfully built and installed a vb.net application with one form like the one in the Deploying Application Article by Jayesh Jain. It ran fine when I installed it on other computers.

But, when i tried to do the setup and deployment stuff for a application with multiple forms, and a access database, and a crystal report it built the setup fine but when i installed it on another computer after i installed it and tried to run it i got a
msg box with:

I have the .net frame work installed on the computers im installing my application on

"Unhandled Exception error
Process id = 0x470(1136)
Thread id=0x484(1156)"

any suggestions?

Im not sure if i have to add anything to the setup because im using a database or crystal report

im using ole db jet 4.0 provider for my connection with the database
