WHen I created the custom install package as per your suggestion above, it give me this error message before it prompt me for the installation wizard:
This installation package could not be opened. Verify that the package exists and that you can access it, or contact the application vendor to verify that this is a valid Windows Installer package.
and this is the contant of the SEP_INST.log
