I bought Office Professional in February. I installed it without uninstalling my old Office 2007 and had no problems running the new Office until today. In short, due to problems with Excel which may have been the result of a conflict between the new Office and the old version today I uninstalled the old Office but the process also uninstalled the new Office. I re-installed the new Office and was informed that it had been installed. Unfortunately I can't find it on my computer though I can access it through the cloud, which is not satisfactory. What am I missing?
