I have Mac Version of office 2011. Can I install that in Ubuntu 14.04LTS?
It is not possible because we don't have any good compatibility layer that supports MAC OS X programs well. The closest, and only one would be Darling. Sadly, it can only run basic hello world programs. WINE does support Windows programs well, but not MAC OS X programs. So if you have the Windows version. You can run it in WINE.
