Hi Kyle Can't understand your post on Photoshop CS4 -- I installed the extended version without a hitch on both X-32 and X-64 systems --works like a DREAM compared with VISTA - I'm running this on a Laptop where I've chucked out the 2 X 1GB Ram cards and installed 2 X 2GB (4GB). Windows update still working FINE. BTW I'm a Professional Photographer and LOADS of people on a photography forum (fredmiranda.com: Specialized in Canon - Nikon SLR Cameras, Forum, Photoshop Plugins, Actions, Reviews, Hosting and Digital Darkroom) are using Windows 7. Since especially for Pro shooters Photoshop is probably the most widely used imaging program on the planet I think there would be some serious concerns if there were any serious problems with it. I use it DAILY and apart from some very specialized 3rd party plugins I've had not a squeak of bother with Photoshop. Here's a screen shot of what I've installed on W7 and a screenshot of CS4 running -- at the bottom right of the image you can see the Windows 7 marker What DOESN'T work is Alcohol 52% - you keep getting the install screen over and over again after request for re-boot. The problem is something to do with the "Virtual SCSI" interface Alcohol is trying to use so you can mount a virtual CD image.
