Run as an existing non-admin user, and ask the remote upgrader installer to promote it to local administrator
Describes how to promote a non admin user to a local administrator
If you don’t have an admin user, but want the remote upgrader installer to automatically promote this user to local admin, user the -SET_ADMIN_USER option. This command will elevate permission for the user, use it with caution.
./bin/install.ps1 -AGREETOLICENSE -LOGON_USERNAME <username> -LOGON_PASSWORD <password> -SET_ADMIN_USER.
