Hi,
Did you check under the following version locations:
Mac OS X
- 10.6 (Snow Leopard): Dock
- 10.7 (Lion): Dock and Launchpad
- 10.8 (Mountain Lion): Dock and Launchpad
- 10.9 (Mavericks): Dock and Launchpad
- 10.10 (Yosemite): You can start the apps by clicking the app icons which can be found in the Launchpad and Apps folder in Finder.
If not I will suggest you to raise a support case with Microsoft as the download should include all the apps under M365 Business, perform a clean install if possible.
Hope this helps.
