But that's not what I'm trying to do.
Whenever a program installs, it has the front end- the exe, plugins, sound files, etc. Yet, in a lot of cases, it installs things into the registry, windows file, and system32. Installing to the flash drive wouldn't be able to do anything with those three files. It would be like... if you installed PJ64 to a floppy disk (I know it's not small enough to fit on a floppy), taking it to a computer that's NEVER had PJ64 installed on it, and trying to run it off the floppy without installing it.
That's what I'm trying to do.
