I got around to upgrading to Office 2013 from 2010 today on my Windows 8 machine and ran into an issue with the “Windows Font Cache Service.” I didn’t think to screenshot the error, but it occurred right after I chose the options I wanted and clicked the ‘Upgrade’ button. The installer didn’t hang, it just wasn’t able to progress at all and gave me the message about being unable to stop the service. I tried to stop it manually from the services management console, which failed with an error stating it couldn’t be stopped and to contact my system administrator.
I’m not one to carry on conversations with myself so I did some searching and most of the results said to uninstall the previous version before installing 2013, but there’s an easier way…
