Retail Windows 7 Proffessional and Dual Boot XP Pro

[grimreaper111]

My computer has two separate hard drives, one with XP Pro 32 bit and one with Windows 7 Pro 64 bit. This dual boot system works with no problems.
My question is this. I brought Window 7 Pro retail pack that includes both 64 and 32 bit disks. I want to change my XP Pro 32 bit to Windows 7 Pro 32 bit. Can I use my Windows 7 Pro 32 bit disk and be able to activate it so I have Windows 7 Pro 32 and 64 bit on separate disks but on the same computer or do I need to buy another Window 7 retail pack?
Note that the Windows 7 Pro pack is the full Retail Full Package Product (FPP)

You aren't allowed to have Win7 32 & 64-bit versions installed simultaneously using same licence & key.

Thank you. I have just looked at microsoft's shop but I cannot find where to buy a second licence. Where can I buy a second licence or do I have to buy another retail pack?

You'll have to buy the Retail one. You can't but just the license key for Win 7 any more.
