    Office - intall 32 or 64 bit version?


    I need to do a clean install of my operating system because of problems I am having with MS Office. Right now I am running the 32bit version and I wonder if I should install the 64bit version?

    Stay with 32 bit unless you have huge spreadsheets. 64 bit is not needed normally for office, and usually causes more issues.

    Microsoft recommends the 32 bit version of Office unless you have a specific need for the 64 bit version, such as working with very large data sets. The 32 bit version will be installed by default, even with a 64 bit OS. The 32 bit version provides better compatibility with other applications and add-ons. See this for more information:

    I had an issue the first time I installed the 64-bit version of Office 2010, first version it was available as either. I had a warning message to uninstall any 32-bit part of Office 2003 first, all I had left installed was FrontPage 2003 so removed it. It was a coincidence that my Domain Hosting Service announced discontinuing support of FrontPage extensions at about the same time so I went with Expression Web. The Office 64-bit version works fine.

    Thanks for the replies. I am having problems with Outlook so I uninstalled it, removed the Outlook files and then installed the 64 bit version to see if it would improve things and it did not. I forgot that my Frontpage 2003 is 32 bit and I want to keep it around. My next step is to format my drive C: and do a clean install.

    If you ever want to export Office to another program such as Thunderbird, the 32 bit version is necessary. Thunderbird is 32 bit and will not convert from 64 bit Office.

    After a clean install of Windows 10 PRO 64bit I installed Office 32bit again. I managed to import my old data files and Outlook is working perfectly again. Thunderbird is good but I am too used to Outlook.

    I had not done a clean Windows install in more than a year; it really makes a difference to a lot of things. After 3 days of installing programs I am starting to see the light at the end of the tunnel. :)
