Even if you copy it... it won't work without the registry, serial number, activation key, etc.... Adobe has Anti-Piracy measure on their software..... there are easier ways to get Adobe CS3.
yeah i dont know how to copy a program thats already installed....you need the installation files and they arent hard to find online anyways....if you cant get them then maybe you should just pay for it or steal the hard drive out your school computer lol....
do what i did, i downloaded adobe cs3 and illustrator into my USB thumbdrive.. im running the portable versions so i can just plug the drive into the usb and run it on any windows computer.
