32 bit to 64 bit upgrade RRS feed

  • Question

  • Hi,

    I bought a 3-license upgrade of Windows 7 Home Premium, and so far I have updated two computers, one to a 64 bit and one to a 32 bit system.  I have since realized that I could have upgraded my 32 bit computer to a 64 bit system. 

    If I now upgrade my 32 bit system to a 64 bit system, is that my third use of my license?

  • Thank you for your reply.

    I was already aware that I would have to do a custom install for the 64 bit version.  I am prepared to do that.  However, I need to understand how installing the 64 bit (after installing the 32 bit version and changing my mind) will be counted on my 3 computer license.

    My question was:  I had already upgraded from 32 bit Vista to 32 bit Windows 7, and then realized that I could have (and should have) done a custom install of 64 bit Windows 7.  Will the custom installation of the 64 bit system count as one of the 3 uses of my license?  If I change my mind on which system to install on one computer, is my second choice counted as a second use of the license?  Or can I still upgrade two more computers after I installed two versions of Windows 7 on one computer?

    Thank you for your help.

  • Hello brianh7658,

      I am not a licensing expert (i'm technical support) but my understanding is if you are allowed (by the End User Licensing Agreement) to have three copies of Windows 7 Home Premium, then you can have three copies of Windows 7 Home Premium regardless of wheather the three are of 64bit, 32bit or a mix of the two.

    Thank you,

  • Hello brianh7658

    I am in the same situation having put a 32 bit on my computer and after validation, decided I should have used the 64 bit version..... so my question is, can I 'un-validate' it to allow me to install the 64 bit without wasting a licence.
