It seems like C2R does not remove Office 2010 beta from my computer which makes it impossible to install another or older version of Office.
the C2R removal file listed in other topics is not available and uninstall software from 3rd parties also does not work. This link is dead:
I tried the Progamms & Features deinstallation function which didnt not work it just says it will take some minutes to do so but in the end it runs for hours (!) and nothing happens - I have to restart...
