Help setting up restore cd for windows xp pro

Hello,
my windows Vista crashed...with advice, I USED A windows XP PRO set up to reinstall..if possible, but
the cd was a 64 bit..did not know..my computer uses a 32 bit...now I cant get the 64 to uninstall off my computer..so I can use my windows setup/ 32 bit..
said not enough memory for 64bit..how do I get the windows set up cd off my computer to be able to run the windows 32 bit setup cd..thank you

Hello and welcome to Tom's Hardware Forums

I've lost track of this just a bit - you had both 32 and 64 bit XP CDs? If that's so, and in the unlikely event a 64 bit could have possibly installed in a 32 bit system, just pop the 32 bit in and follow the instructions through to formatting the hard disk and reinstalling afresh.
