    Hello,

    I have searched incessantly for this answer and can't seem to find one article that addresses it in the way I am asking.  I have windows 7 professional 32 bit installed.  I want to simply upgrade either to windows 7 64 bit pro or ultimate.  My first question, is can I just buy the pro to ultimate upgrade, select 64bit when I go to install and get a clean install that way.  Or 2, what do I need to do and what is the minimum I need to buy to change my OS from 32 bit to 64.

    I've found a ton of info but it usually is referencing going from XP or Vista or it simply says do a clean install of windows 7 64 bit with no reference to what product I actually need.

    I had originally used one of those student online purchases so all I had was the 32 bit and do not possess a 64 bit version so it's important to understand whether I can use an upgrade or must buy a full install, etc.

    I appreciate your help.

    Eric

    Hi,

     

    Cross-architecture in-place upgrades (for example, x86 to x64) are not supported. You need to purchase a full version of Windows 7 Ultimate x64 or install Windows 7 Professional x64 before upgrading to Windows 7 Ultimate x64. In addition, you can use the current product key to activate Windows 7 Professional x64.

    I believe that you could use your current key to activate an X64 version of Win7 Pro. (You may have to activate by telephone, as the key is already in use.)

    It may be a violation of site policy to post links to downloadable versions of Win7, but a few seconds with my favorite search engine showed a site with links to what appear to be the standard .iso. (Not hacked - a legitimate key would be needed to activate.) Size: 3.0GB.

    Alternately, if you have a chum with an X64 install DVD, you could copy it. If it's not for Pro, supposedly it can be made generic by removing the ei.cfg file. (The Home version is supposed to contain the Ultimate code, to allow the Anytime Upgrade.)

    You shouldn't have to spend any additional funds, or violate your license agreement.

    Can I install the 64bit version on a separate partition?

    The reason for asking is because I do not have an external drive to back-up my data. And some of my programs do not have CD's or DVD's any more, so I will loose the programs if I have to format my hard drive.

    If this is a dumb question, please do not shoot me, just give me a straight forward and simple answer for someone that is not very software literate...
