If you downloaded the Mac version of MS Office, there should be 2 folders on the bar that has icons on it documents and downloads folder. If not open the Macintosh HD icon on your screen, click on it again in the drop down menu, and then click on Applications. Scroll down to MS Office. I have a Mac Pro --- assume you have the Intel OS also. Hope this helps. It is a hit and miss answer if you don't post which Mac you have and the OS you are using in it.
Total Mac newbie here.
I have downloaded microsoft office and the update with remote desktop.
Trouble is I can't find remote desktop on my hard drive.
