Office Updates for Mac OS X
To update Microsoft Office for Mac OS X, do the following:
Make sure you have a working Internet connection.
Open any Microsoft Office application (Word, PowerPoint, Excel, etc.). You do not have to do this for each program; Microsoft AutoUpdate will download updates for all Office products.
Click [Help] > [Check for Updates].
Click [Check for Updates]. Software updates appear in the Microsoft AutoUpdatewindow.
5a. Note: You will need to close the Microsoft application you opened in step 2 in order to be able to download any updates to that application.
More updates may still be available. Repeat steps 1 through 6 until the Microsoft AutoUpdate window says, “There are no updates available for your Microsoft software at this time.”
When you are done, click on the [AutoUpdate] menu and select [Quit].
Note: You do not have to do this for each Microsoft Office Application. Microsoft AutoUpdate will download updates for all Office products regardless of the program you opened for step 2 above.
