64-bit Windows 7 will require an x64 processor. You can't upgrade from XP to windows 7 so If your computer has a x64 processor install the 64-bit Windows 7. It's better than the 32-bit version and more secure.

When you say clean install, I assume you mean you want to wipe the drive clean and install Windows 7 like it was going onto a brand new empty hard drive. Assuming the hardware will support the OS, you need to boot from the installation CD. There should be a point early on in the installation process that asks you what partition and stuff you want to load to. You should see the existing partition, and have the option to delete it and then create a new one to install 7 to. XP is telling you the disc isn't a valid 32bit application, because it isn't. it's 64 bit ;) But if the Windows 7 disc is a full installation disc and not an upgrade, you should be able to boot from it. It is just a matter of going into setup (bios) and telling the system that the DVD/CDROM drive is the first boot device.

You can't load an operating system onto an operating system. I heard that win 7 will come with both 32 bit and 64 bit versions so you can just install the 32 bit one but I'm not sure if that's true. What you want to do is do dual boot, you need to get another harddrive and install the operating system on that. Just make sure that your CPU will handle a 64 bit operating system, it should but just double check before installing.

First off, please note that when migrating from Windows XP to Windows 7 you will not have an "in place upgrade" option. You will however have the option to select "custom" install when prompted. The Windows 7 install process will then copy all of your data in "My Documents" over to a Windows.old folder within Windows 7 itself. All applications and documents stored in other locations will have to be reinstalled / transferred manually.

You also cannot upgrade a 32-bit operating system to 64-bit -- to migrate from 32-bit to 64-bit will require a custom install.

in order for any 64 bit operating system to work on any computer the processor needs to be a 64 bit processor and you need atleast 4 GB of RAM. 64 bit operating systems run off of 2 GB or RAM.

it more than likely wont even try and install it and if it does it wont work... its a bad idea! tell microsoft what happened, they might do a swap.

unless you have the hardware for a 64 bit opp, but tbh if you have an average store computer, you probably dont.

If you have the right computer specs, nothing. Upgrading from 32bit to 64bit is harmless

Dont do it that would lead to epic failure

Won't work.
