When I try to add programs to the U3 Launchpad the following appears in an error window, “U3 launchpad failed to install U3 program, due to a possible error in the program package.” What is the problem?

This problem can happen when the program being installed is not a U3 Smart Application.

U3 Smart Applications normally end in .U3P, only some end in .exe.

It is not possible to install non-U3 Applications to the U3 Launchpad.
