Office 2013 is currently in beta or Preview as Microsoft calls it, and is available to the public as well as MSDN and TechNet subscribers. I recently installed it on a fresh Windows 8 system, and didn’t include all of the programs that the suite offers. When you start the installation, choose the Custom option to install only the programs you need.

After you’ve done a custom install of Office, you might find later that you need another program offered in the suite. Here’s how to add them in Office 2013. For this article I’m using Office Professional Plus 2013 Preview, but the process is virtually the same for all versions.

On the next screen click the dropdown menu next to the program(s) you want to add. Here I ‘m adding Outlook 2013. Click Run from My Computer then Continue.

Now wait while the program(s) are configured and installed.

Success! Close out of the complete windows and restart any Office programs that may have been running.

Now you’ll find the new program icons in the Start menu or Start screen on Windows 8. In Windows 8, the first thing I do is pin the new Office program to the desktop taskbar from the Start screen. See how to Disable Startup Screen in Office 2013.
