Answer 1

Perhaps you have some referenced assemblies that you did not copy along with the application itself.

OR, the connection string is not valid when run from that other machine (if you worked with a local SQL db, or on a network or whatever and it's not accesible on that other machine)

OR, you don't have rights to run it on that other machine.
