Its exe file is small and it actually has a portable registry file.
I just need to copy and paste the 'PhotoshopCS4 Portable' folder (no rar or zip required) on a USB to another computer. The AP CS4 can run on my Windows Vista, 7 desktop and 8 computers. They are both portable in the sense that they don't require installation. I have two versions of 'portable' application, which I have downloaded a long time ago. Cameyo also compiles it too much and acts as a 'middleware' whenever you want to open ThinApp VMWare compiles the whole application into one exe file, which doesn't always run on other computer. I found that apps like Cameyo and ThinApp VMWare, but they are not really portable. I did some research on how I can make an application portable and they all require an image capture of the installation before and after.
