Adobe Photoshop CS4 Extended won't install from CD
I purchased Adobe Photoshop CS4 a few years back and installed it onto my PowerMac G5 Tower (pre-intel). Now I'd like to instal the program on my MacBook Pro (OsX, 10.6.8).
QUESTIONS:
1. Is it not compatible?
2. What is the current version of Adobe Photoshop that I should be running on the Macbook Pro?
3. Must I pay for the whole program again?
