I upgraded a 64 bit Windows 7 laptop to Windows 8 through the Upgrade Assistant, creating a bootable USB without any problems. I installed it successfully. Before I purchased an upgrade for my 32 bit Windows 7 laptop, I decided to boot from the USB with the 64 bit ISO to see what happened. The Windows 8 install screen came up with all the options. Should it not have detected that the laptop is 32 bit and therefore the install should have given an error?

I cancelled the install before it did anything, but now I want to know if I need to download the iso again after purchasing the upgrade on my 32 bit laptop? I've read the answers to this question, which confirms what is said in this article - a 32 or 64 bit iso will be downloaded depending on the hardware of the computer you are upgrading. If that is the case, then why did it boot into the install screen?

I haven't personally tried this, but I believe from rumors that the x64 installer will launch on a 32 bit system, but I don't think it will let you do anything. Unless it is really a 64bit processor - then it will let you install/upgrade.

So to have a complete answer - the legal/legit versions of Windows do not have 32 bit/64 bit on the same media. I have heard of illegal/non-legit versions floating where they combined both (supposedly via a boot option) - of course I would never advise downloading such copies but that information is just here for completeness.

Why would it? If you proceeded through the installation it would have wiped the 32-bit operating system.

If you want to upgrade your 32-bit Windows 7 installation you will need to download the x86 iso. The license key can be used for either installation.

ok, it's just having a capped Internet connection is a nightmare. –  Arabella Nov 3 '12 at 22:16
    
@Arabella - I don't know where you live but there are many alternatives to whatever internet connection you have. Clear comes to mind. You could ask that question on here :). –  Nathan Adams Nov 3 '12 at 22:26

That just means the boot up is not 64 bits and is shared. I've had this when I've inserted the wrong dvd and I boot then start the upgrade. Only to be told a moment later it's the wrong one.
