Actually it's rather easy: Go get ThinApp from VMWare, it only costs $4,999.00 dollars. Run a fresh install of windows and have ThinApp monitor the Photoshop installation. It will then build you a portable version of Photoshop. Seriously thats the only way you'll get it to work right. This kind of app was never designed to be portable and the newer adobe apps even write to you MBR when installing. Thats why the "warez" version is so popular because they don't pay for this crap and then they get the neat toys. Also please don't ask how to aquire the warez version as it is very against the rules and we don't support warez.
