Mountain Lion and Microsoft Office

Office 2004 and older aren't supported because OS X Mountain Lion isn't compatible with PowerPC applications. Now, you can upgrade to Office 2011 and get the newest Office version with all its features > http://www.microsoft.com/mac

Office is the most complete productivity suite for Mac, so if you need a lot of features, buy it. Then, you can go with other apps:

1. Apple iWork: available in the Mac App Store, it includes Numbers, Pages and Keynote. It's easier and has got less features than Office.

2. LibreOffice: free and open-source > http://www.libreoffice.org If you don't want to pay for Office, install this application

What version of Office do you have? Office 2008 or 2011 will work with Mountain Lion. Office 2004 will not work because it is a PowerPC application and PowerPC applications are not supported in Lion or Mountain Lion. Some Office alternatives.
