In Office 2016 and Office 2013 you can’t custom select which Office applications you want to install. However, you can delete shortcuts to applications you don’t plan to use.
Also, you can only install Office on the system drive where your operating system is installed. That’s usually your C: drive.
Tip: If you decide you want to purchase a stand-alone Office application, you can go to the Microsoft Store at https://www.microsoft.com and do a search for the application you want to buy.
