I just bought CS4 Extended for my computer. I made sure all of my other photoshop programs were removed. I put the disk in, but the auto play wouldn't work. I ran set up manually as an administrator. The program launched and a screen stating checking system came up. After getting about 90% down, the screen changed and said loading setup. That screen just flashed for a brief second and disappeared. Nothing else happened.
I decided to try installing on my laptop, which has Windows Xp, and autoplay worked, and the program installed without a problem. So, is there a configuration I need to change on Vista? Thanks.
