During this latest Microsoft update, following a worldwide publicized chip problem – which does not affect the GT controller, I know of a test controller here and at least of one controller in the field where the GT application does not start as usual, starting the central_controller brings the message.
The reason is that the Microsoft update does not allow the underlying real-time kernel RTX to start.
The maker of RTX is analyzing the situation and a fix is planned in the future.
The most important now is that you do not update the operating system.
If you are down, you will have to reclone the partition C:/ with a prior version. We will an ISO disk for Acronis ghost and a restore for partition C:/ available. Contact email@example.com if you need the links to it.
Make sure not to update the operating system
Go to Control Panel/Windows update and make sure with Change Settings to set it on “Never check for updates”.
DO NOT press check for updates.
You should not have the GT-controller connected to the world-wide-web anyway.
