UGS - Classic or Platform

I just installed the latest nightly build for Platform. I’ve installed the latest 64bit java. The program comes up.
I’m using a Windows 7, 64bit

I used the setup wizard, set to the same setting for my controler, as from the device manager.

  1. GRBL
  2. 9600
  3. Com4

It says connecting, then it says the setup wizard is not supported for this controller.

It is connected in some way to the controller. If I hit the connect/disconnect button, it will says in the console, that it is connected on com4 at 9600 baud.
If I hit the button again to disconnect, it says connection closed in the console and I hear a noise from the xcarve stepper.

Any help please.
