Comodo - Not a valid Win32 application - Fresh XP InStall

After having some problems with my computer I did a total fresh install of Windows. My XP Pro SP2 install disk was scratched, so I pullled out my older SP1 Pro disk and got Windows back on the computer. Also, I accidentally erased/formatted my second drive so BOTH 80gb drives are clean.

I got Avast back on, and my D-Link Wireless reinstalled. I also ran the upgrade to SP2. But when I try to install Comodo I get the “not a valid Win32 application” message. Then it says I maybe don’t have enough memory. I first tried to install CPF 3, then I tried CPF 2. Both give the same message.

Any ideas?
