You must be an administrator on the computer where you want to install Microsoft 365, Office 2019, Office 2016, or Office 2013.
If you're not already an admin, when the User Account Control windows appears during the Office installation, a person with administrator rights on your computer must type in their admin username and password, and then select Yes for the installation to continue.
How to check if you're an administrator
How you check if you have administrator privileges on your computer and what to do if you don't, depends whether or not your computer is joined to a domain.
Tip:Â A domain is a way for the network administrator of an organization (such as your work or school) to manage all the computers in their environment. Not sure your computer is or isn't joined to a domain? Do the following: Open the Control Panel and then select System and Security > System. At the bottom of the View basic information about your computer section, if you're joined to a domain it says, Domain: and lists the name of the domain you're joined to. If you're not joined to a domain, it says Workgroup: and indicates name of the workgroup your computer is part of.
