Office 365 ProPlus install - should we remove Office 2013 Home and Business first?


  • We have multiple users, including myself with Office 2013 Home and Business.  In addition, I have Visio Pro 2013.  We are trialing Office 365 E3 right now, wanting to demo the Lync features especially.

    When I went to install Office 365 ProPlus from the My Apps page, the ClickToRun app started and then eventually after streaming for about 2 hours simply froze.

    Rebooting didn't help and I was forced to Uninstall all Office 2013 apps using the following KB article's "fix it":

    My question is:

    Is there a proper rollout for getting users that already have Office 2013 (either the full suite or individual apps like Visio) upgraded/migrated to Office 2013 ProPlus with the E3 plan of Office 365?

    Is it going to require uninstalling existing Office 2013 suites/apps on their PCs before running the installer on the Office 365 site?  Or, should the Office 2013 ProPlus be able to upgrade/replace the existing Office 2013 suites/apps on a user's PC?

  • Hi,

    It might be caused by conflict between the two Click-to-Run installations.

    In the situation, check if the .msi based installation is available for Office 365 ProPlus. Maybe they can installed on the same computer as per:

  • You can install Office 365 along side local installs of any version Office, 2013 and earlier.  You can actually setup the 365 installation to connect to the local install.

    I have been reading about conflicts between 365 installations of Office and Visio and Project.

    maybe the deployment guide will help
