Can a 64-bit Home Premium license/key also install the 32-bit version? RRS feed

  • Question

  • Without really thinking about it, I purchased the 64-bit version of Vista (Home Premium) along with the parts for my new computer. Now that I've read around, I fear that I may have some compatibility issues. In case I do, is it possible to install a 32-bit version of the same edition using my 64-bit key? Or would I have to install XP and basically be stuck with a useless $140 purchase?

    The license key will work.


    To check compatibility try the HCL (Hardware Compatibility List):







    You can also test your new system automagically with the Upgrade Advisoor

  • I have the same issue.


    I recently upgraded my HP Pavilion dv5157eu to Windows Vista 64-bit. The notebook does have a Vista capable sticker and passed the "Microsoft upgrade advisor".

    The machine is running quicker than it was on Windows XP and I am truly impressed.

    However none of the following works:

    - Conexant AC-Link Audio
    - Conexant AC97 Soft Data/Fax Modem with SmartCP
    - Quick Launch Buttons
    - Texas Instruments Media Card Reader

    I have searched the internet for 2 weeks and have had various communications with HP, each time I get a different solution of which none have worked.

    Please can someone tell me where I can get these drivers? Surely HP should have developed drivers for their Vista capable notebooks!?


    Now I am stuck with Vista x64 Home Premium!!! I want to install Vista x32 but don't have a disc and am unsure if the key will work? Please let me know if you were able to install x32 from a x64 disc?

    Huh, I just got an email on this thread, was not expecting that. Anyways, what hardware are you having an issue with exactly? You should probably contact your manufacturer...

    I ended up having no issues whatsoever with x64 Vista. It's running quite smoothly.
