Im having a problem with installing Adobe Photoshop CS4. I downloaded the trial from Adobe website and when i try to install, it says:
"Setup encountered an error and can not continue. Please contact Adobe support" I have administrator rights and running the exe. as an administrator. I'm using Windows Vista Home Premium 32-bit version. Any help?

Have you tried re-downloading the file?

Yes, I have, but it didn't work any better...

I've had this problem before and it's not directly a Vista erroer as I had it on XP.

I think I fixed it by manually extracting the files from the zip you download with WinRAR. I think that's how I solved it.
