From what I've read, Photoshop isn't really 64 bit yet, so there would just be the 32 bit installer.

That could be part of the problem...

Nick, how many gigs of ram does your system have? Since you went with V64, I'm going to guess that you have 4GB+?

Vista 32 can only handle 3.2GB of ram, as that's the limit of memory addressing for a 32-bit OS. If your V64 system has 4GB+ of ram, then it might screw up 32-bit installers. If there is any sort of memory check in the installer, and V64 reports 4+GB, it's possible that the installer will blow up.

If you have more than 3.2GB of ram in your system, if you can, remove memory to get your system below 3.2GB. If you have 4GB, then the common setup would be to have 2, 2GB sticks. Remove one of them and just run with 2GB. Yes, your system will run a little bit slower, but it should be fine. Then try the installer. If it works, install, shut-down, and put your memory back in.

Just a theory...

Yeah, I've got two 2GB sticks. I will pull one out and try installing again. So far, I have an open "case number" with Adobe, but no answers yet...
UAC is already off, and yes, I am on SP1...

ok i've never posted here before, but i am having the same problem with Photoshop CS3 and internal error 275. i've been pulling my hair out all night over it. i tried the "RegCure" crap and that didn't do anything, tried another CCleaner registry cleaner and that didn't help either. i've found numerous sites mentioning bad Ram...but it doesn't seem to be the case.

oh and i'm not using Vista, still on XP...UGH.

Why don't you think it's bad ram? I've had that happen a few times. Worth a few passes of memtest86, just to be sure.

New installer got me going. Contact Adobe support. They will need your valid registration key info and such...
