Install the Admin App on Windows

For Windows 10 or later on x64 computers. For a first trial, you can also open Web Admin without installing anything.

Open Software Downloads → Admin installers and select the Windows Admin package.
Run the installer if supplied. For a ZIP package, extract the whole archive to a folder before launching the application inside; keep its companion files together.
Open the Admin app and sign in to the account managing your devices.

The picture below shows a portable package. Folder and executable names can differ between releases.
