You might be able to just copy the installed directory i.e. program files/adobe/photshop or whatever onto your drive... It won't be truely portable, but it might well run fine, even if it leaves traces on host PC. This works for a few apps that I have tried...
Also, I have downloaded and checked out most of those portable versions on the torrent sites, and they are usualy just a slightly changed version of my portable PS 7.0 launcher with the program added. 2 things makes this illeagal:
Thanks for the detailed info, Deuce. I had my doubts too about the true portability of that program. There are actually quite a few more quite famous programs to be had over torrent that seem to work without installation and which they distribute as "portable", and I think those, too, wont work without making heavy use of the registry and writing files into the system, given the nature of some of the programs. Just don't want to mention their names here.
I just downloaded photoshop 6.0 from bittorrent and it was already portable. i could zip it and send email it to you or something if you want, but it's about 100 megs so you would need gmail or something to dl it. just email me email@example.com and i can help you out 2b1af7f3a8
