I'm configuring a GPO to install Office 2013 on my user's machines. Some of them already have Office 2013 installed on them from being new or when they had to be reimaged. My custom.msp (created using OCT) is configured with the default state to remove existing office installations before installing Office 2013. My question is, will the Office 2013 setup recognize an existing 2013 installation and halt (silently) or will it just see an Office installation and uninstall whatever the existing Office is and (re)install Office 2013?
Preferably, I'd like to just set the GPO to run at the top level of the domain and apply to all the PCs in the organization but I don't want it spending 10 extra minutes on the login/logoff screen uninstalling an existing Office 2013 installation just to reinstall the same thing and have the user go through all the wizards again.
