    Changing Office from 32 bit to 64 bit


    I am running the 32 bit edition of Office 2016 Pro 32 on my PC which has a 64 bit processor.
    Do I have to purchase a new (64 bit) version of Office to take advantage of my 64 bit CPU?

    Thanks in advance to all who reply,
    Dan

    No you do not need a new key to change the Arch of your software... the product key is for both x86 (32 Bit) and x64 (64 Bit) versions...

    Deb,
    Sorry that I wasn't clear, but I'm already running Win 10 Pro 64 bit - it's the Office 2016 that is running 32 bit (which I would like to change to 64 bit).

    Kyhi,
    So are you saying that I have to re-install Office or is there a more convenient way to do it?

    Think carefully before choosing which version to use, there are pros and cons for each. Yes, you must uninstall the 32-bit version before installing 64-bits. More here....

    Microsoft Office said:
    Important: If you already installed the 32-bit version, but want to install the 64-bit version instead (or vice versa), you must uninstall the version you don't want before installing the version you do want. See “Office (64-bit or 32-bit) couldn’t be installed” error when trying to install....

    ...IT Professionals and developers in particular, should also review the following situations where the 32-bit version of Office is still the best choice for you or your organization...
    Choose between the 64-bit or 32-bit version of Office
