This is the full adobe photoshop cs3 in a 50mb package...
It is not portable!!! It is the full version
To install you simply extract the rar to C:/Program Files/Adobe Photoshop
And then create a shortcut to photoshop.exe inside that folder and put it in your desktop
This version of photoshop has all the features working and in perfect order...
It is amazing and it is what I use for all my editing
It is only 50mb so please download as free user
