I think InstallJammer would be improved if you disabled or removed "Exit" in "Startup Actions," which displays the now useless "This will install Your Application Name on your computer. Continue?" window before the Welcome Screen.
The simple work around of setting Active to No works for me. I'm reporting this to improve InstallJammer for everybody else.
