Hi Sai,
I'm sorry for my first reply that just provides a link for Office updates. However, about how to download Office 2011 for Mac is in the second reply, just as SiddNair needs.
If you have an Office Professional Plus license for Office 365, you can log into your Office 365 web page, locate the software page, and click install under Office to install the latest version of Office.
Best regards,
Cherry Wang
