The thing that would help people use the software at friend's computers/kiosks/etc. would be the ability to chose a download that DOESN'T "install" as it does now, but it just extracts its files to a user-defined location and that would be "installed" onto a jump drive/flash drive/ZIP/floppy/CD/etc. It might also be a good idea to make the files smaller in size, or take out features to allow for floppy installation (yep, I use floppys on occasion).
Note:
(Mouser, I'm posting this here simply because as your programs are the "biggest", they require an install.)
