This is a portable version of Adobe Photoshop CS6, which I use. It has everything the original CS6 is capable of, only that you're spared from installing, cracking or license key woes.

Just download the rar file, extract, keep the folder somewhere (I keep mine on desktop for easy access) and poof. No installation, no fuss.
