Windows 7: Photoshop CS4 Compatibility

I've attempted to install the CS4 Extended trial software several times over the last hour or so, utilizing ever compatibility combination I could think of and I still get the same error ("A problem occurred while extracting some files. Check available space on your computer and write privileges on the destination folder.") no matter what my settings are. I currently have 451GB of free space and I've attempted the initial extraction logged in as the admin with "Run as administrator" selected in compatibility with no effect. Can anyone help?

Photoshop CS4 seems to be compatible with Windows 7, may be you've got some damages installation file, have you used it previously? Also if you have two or more ogical drives try installing on the one WIndows 7 is not installed on.

Photoshop works great on windows 7, I got the whole master collection installed and works fine.

I thinks the problem is only with the 64bit version of Windows 7.

Nope dude I have Windows 7 64bits new installation and A. Photoshop CS4 works great, only I have a problem with photoshop 64bits

I can run both 32 and 64 bit Photoshop just fine and I have the Master Collection.
