    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

    :)

  2. Switch from 32 bit to 64 bit

    Switching from 32 bit to 64 bit, will it erase my data from my 32 bit Office when I uninstall it to install the 64 bit Office?

    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...

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

    you have uninstall 32 bit and install 64 bit

    you can try running 64 bit installer - but feel you will get error

    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....

    Choose between the 64-bit or 32-bit version of Office

    Does the 64 bit version offer much practical advantage over the 32 bit version which is installed by default?
