BC 32 or 64 bit for XP prior to Win 7??

Question

I downloaded the 64 bit Boot camp update but it will not install, even using the winRar extraction technique suggested in another thread. Since XP Professional is 32 bit, I assume only the 32 bit update will work, so I used that....
BUT does that mean that when I install Win7 64 bit that it will not work????
Or can I install / reinstall the 64 bit over top of the 32 bit once I have upgraded to Win 7...
For lack of instructions for these 2 releases and proper procedure, Apple support gets a D-

Hey all, deeseeArch here,
What I did worked for me on the newest MacBook Pro Unibody. Here it is:
As I said in my post, I did not have windows or boot camp installed on my computer prior to this. Not because I erased it, I just never had done it before.
1. In Mac OSX I started up Boot Camp Assistant. I created a 60 GB Partition. That went smoothly.
2. When prompted, I inserted Windows 7 Ultimate DVD and hit Start Installation. Windows installed fine.
3. In Windows 7, I inserted the gray Mac OSX Install DVD, and setup.exe started automatically. This installed BC 2.1.
4. In Windows 7, I now inserted my Snow Leopard DVD, and setup.exe started automatically. This installed BC 3.0.
5. I downloaded the new BC 3.1 file from Apple site (the x64 version).
6. I double clicked that file and ran it. This installed BC 3.1.
So far everything is working fine. I can see all mac drives, external drives; volume, eject, and brightness keys work. Mighty Mouse works, sound works, display is fine. It's all good.
As I said in my post, I am going to install this on my wife's MBP, older model to see how that goes. Haven't done it yet.
Hope this helps.
