→Connect the bell system
If you currently use Millennium Suite version 4.8 or older, uninstall it using the Windows Add/Remove utility. Your schedule and playlist files will not be deleted.
=== Connect the bell system ===
We used to say, "do not connect the bell system until the Management Suite has been installed." Windows 10 seems to work better if the system is connected. Be sure to allow time for the driver installation to complete before starting Management Suite.
