Windows 7: have w7 32bit but want to upgrade to w7 ult 7 64bit- upgrade path?

Hi,

I have Windows 7 pro 32 bit but need to take advantage of more memory so want to upgrade to ultimate 64 bit. I'm a student and have seen that I can get an upgrade to ultimate 64bit but it says that I cannot do this from Windows 7 at all but can do it from vista business - as per below link

Windows 7 Ultimate: Microsoft Windows 7 Ultimate 64-bit edition

Do you know this to be the case? I have a vista busines recovery disc but am unsure if this will actually install the vista os on my notebook (I have all data that I need backed up on a USB removable hdd so not bothered if it's a clean install). I really need to do this legitimately as the reason I need to upgrade is so that I can install and run virtual machines to do a microsoft course (quite ironic) and would get found out immediately if I didn't choose the correct way to do it.

Any advise would be great - Thanks in advance

You can only do a 64 bit In-Place Upgrade from 64 bit Vista. You will need to do a clean install.
Clean Install with a Upgrade Windows 7 Version

Did the notebook come with Windows7?

Thanks Theog

I've been able to do a clean install. Had to downgrade back to Vista 32bit and could then do a clean install to Windows 7 Ult 64 bit. Keeps all your old files in a windows old file which was handy
