I just purchased Microsoft Office 2011 for MAC and installed it on my rMBP OSX 10.8.2 running Mountain Lion. The installed version from purchase is 14.2.0. I tried installing 14.2.3 but it failed due to a specific file that was not found :
Office 14.2.3 can't be installed on this disk.
A version of the software required to install this update was not found on this volume.
So I went to the site and downloaded 14.2.1, but that didn't install either with the same message. Also tried 14.2.2, but still the same error.
I want to add that the actual installation failed (tried twice), however Office 2011 appeared in the application folders and Word works fine.
Not sure what can be causing this, any idea ?
clean
uninstallation did prompt me to enter the product key again. If you did not delete every single file related to MS, then the product key might still be registered and you may not need to re-enter it.
