Photoshop 5 in Windows 7 x64

Windows 7 with photoshop 5 plus upgrades

I understand this will only work on 32 bit, as I have already installed Windows 7 64 bit, can I install 32 bit without starting afresh with files, progams etc
Hope someone can advise me
Thank you

You can't "downgrade" from x64 to 32-bit w/o custom (clean) install.

Yes, you should be able to run Photoshop with no issues on 64 bit Windows 7.

There are very few 32 bit programs that won't install on the 64 bit Windows.

However, if you Windows 7 32 bit you'll have to do a clean install and reload all your programs, files, etc.

Thanks for your reply.When trying to install photoshop 5 I get a window pop up saying " This version is not compatable with the version of windows you're running".I hav‏e e-mailed Adobe about 3 weeks ago and had no reply. I have also installed WinINSTALL LE MSI Packager but can't understand that one. Also I would really like to stay with 64 bit. It's putting the blockers on my photography as I have used Photoshop for years and had worked up to CS3 with upgrades.It's worked wit XP and Vista.
Once again thanks for help

You might try right-click on the installer and go to: Properties then Compatibility tab and choose: Run this program - XP Service Pack 2 or 3 and see if that works.
