Is it possible to install both 32 bit and 64 bit Office on one Windows 7 instance?

    Question

  • I recently installed 64 bit office, and found out that one of my beloved addins does not work with 64 bit office, it only works with 32 bit office.

    As it turns out, I have a need for both...

    So, is it possible to install both on one Windows 7 instance?

  • Hi,

     

    Maybe u can try this:

    1. install office 2010 x64 in your win OS (64 bits)

    2. enable virtual machine, then install office x86 in virtual machine.

    is this quote:

    Can I install 64-bit and 32-bit versions of Microsoft Office side-by-side?

    No.

    Hope this helps,

  • Yes you can.... This is how I did it...

    I don't know if you have to go through the whole process or you can skip it all

     

    I installed  Office 2010  x64

     

    Then I windows-updated  office 2010, and rebooted as requested by the system... I searched for new updates and the new one was SP1 for Office  2010, I didn't install that one. So that was all about updating

    Then I unstalled all office updates (I didn't reboot)... and then..

    I just started the installation of Office 2007 (32 bits) [32 bits Office 2010 would not install] and installed on a different folder so I can open Word 2007 and Word 2007 at the same time without any issues in the future, and I got no complaints about having a 64 bits version or a newer version installed.

    As I said, I don't know if this "updating 2010" trick was needed.. But i am very pleased to be able to use Word 32 (which i really need for an addin), and being able to use the 64 version when the adding is not needed.

    Good Luck

    Blessings!

  • The only way I know this can be done is by using Virtual Applications.  I have Office 2010 32bit and a Virtual of Office 2010 64 bit.  They will both run side by side, however you do need to have access to MDOP - you do not need a streaming server it can be run in standalone mode.

  • Can I install Office 2010 x64 professional (e.g. Outlook, Excel, etc) and then install 32-bit Visio and Project?

    Is this side-by-side or just mixing the cake a bit?
