NOTE: JPE Launcher is an "old" 0.1.* version of the original JauntePE launchpad. As such, it is no longer being updated and is only included with this release in case you might find it still of some use. The Build Portable and Discovery features should probably not be used without the realization that they will most likely not work as expected and may end up crashing or freezing JPE Launcher. Also, the generic Settings and launch item Properties dialog boxes will most likely not work as expected and may end up trashing one or more of your hard-won manually edited configuration ini files.
JPE Launcher may be used when you don't want to create portable launchers for each application you want to portably run. It's basically a very simple JauntePE-specific application launcher that presents an icon-based list of applications that you add to as needed.
The JauntePE launch settings are kept in a "launchpad" config ini file and most of the "older" JauntePE runtime settings are kept there as well. So, as long as you don't need any special or new features for portably running an application, you don't need to create, or have created for you, any overriding JauntePE config ini files.
The distributed configuration for JPE Launcher already has most, if not all, of the required settings preset for you. All you need to do is add applications to it, which you do by right-clicking somewhere within the launchpad window and selecting Add from the menu.
