XP Pro 64 bit question

Ok I did a search and could'nt find this exact question so im posting it. I am running XP Pro 64 bit and am at a point where I want to switch to 32 bit. I have enjoyed the 64 bit system for the past couple years until recently when I have had a string of compatability issues. Is there any way I can switch over to the 32 bit system without doing a fresh install or is that my only option??? Thanx

 

No my only problems are compatabillity with my camera software. I recently started a photography business and today my Nikon View NX stopped working. What I did to solve THAT issue was un-check the compatabillity for windows xp and now its working but its the little things that have added up. my last HP PCS All In One was working fine but HP did'nt offer drivers for the XP Pro 64 bit just a beta version. I had to buy a whole new printer and im worried im going to come to a point where that will stop working too. I don't want to make the jump to Vista just yet as I am waiting to see how Windows 7 works. I really like XP Pro and would like to keep using it as long as I can. Thanx!!
