When trying to install Microsoft Office Professional Plus 2010, I lost two hours as the installer stopped at some point and told me: “Microsoft Office Professional Plus 2010 encountered an error during setup.” (to be exact it was “Microsoft Office Professional Plus 2010 hat bei der Installation einen Fehler festgestellt” as I installed the german version).
I sadly didn’t find the solution, but probably the cause for this problem. I tried to uninstall Kaspersky’s Security Suite before, but didn’t uncheck the “protect this installation” – checkbox in the settings before … which led to Kaspersky not being uninstallable! When I finally managed to uninstall Kaspersky after trying to install Office 2010 (by unchecking the mentioned checkbox), I got some errors during uninstallation … but at least it was possible to uninstall. When I then tried to install Office 2010 again, I got the same errors – but ignoring them this time didn’t work out.
Hope you don’t run into this error.
