The 11.3.2 update is for Office 2004, not for Mac OS X. Here's how you can
get it:
In Office 2004, use Microsoft AutoUpdate to get the latest updates. From
any Office application, go to Help > Check for Updates (or manually launch
Microsoft AutoUpdate from the Applications folder). If any updates are
needed, they will display in a sheet, at which point you can check them and
press the "Install" button to download and install them.
Updates can also be found at the Microsoft web site:

The latest version of Mac OS X is 10.4.8; you can get the latest update(s)
if you need it/them by going to "Software Update" under the Apple menu.
