Ain't happenin'Buy a 64 bit version.
You may have both version on the disc that came with the PC.
Even if you do its the product key that decides what version you can install.
You'll need to fork out for an upgrade.

That looks like a solution, cheers.I've used http://itrevive.co.uk/windows-licences.html a couple of times for licences. Cheap and legit.
Good to know, cheers.If you get a 64bit disc your 32bit licence number on the oem sticker will work They are 2 types of oem discs 32 and 64 the licence number will with either the number will determine the version home pro etc. Its also possible to install from the disc and enter the key later doing this give you a choice which version to install.
going through the same, but similar tonight...upgrading my 16 bit linux to a 32 bit linux install. Oh...and its free just in case I f ck up....
Unfortunatly they're a bunch of idiots. Paid my money, downloaded the iso, but they sent me the wrong product key and now they couldn't care less. Keep saying I must have made a keyboard error.I've used http://itrevive.co.uk/windows-licences.html a couple of times for licences. Cheap and legit.

I think they may not be legit.
Thanks for the suggestion, but I already checked I'd got the right isoMake sure you've got the correct iso (home, pro etc) for the key. I had the same thing before I realised I'd downloaded the wrong iso.
