MS Office 2011 won't install under Mountain Lion
Today I upgraded from Lion to Mountain Lion. However, my MS Office 2011 refused to run, didn't even start so I couldn't check for updates manually. I had it set to check for updates automatically by the way.
So I uninstalled MS Office and then reinstalled from the installation disk. But my iMac won't install it; it starts up the installation most of the times (although it sometimes spits out the disk without even trying) but after several tries it keeps telling me that the installation failed because there is no software to install.
So frustrating!
How can I install it anyway? I really need it since all my documents are MS Office.
