If you are running on Windows 10 (version 1709 or later) then there shouldn't be any problem installing Windows Admin Center 1809.
When you install Windows Admin Center on Windows 10, it uses port 6516 by default, but you have the option to specify a different port. You can also create a desktop shortcut and let Windows Admin Center manage your TrustedHosts.
