No source name visible for NDI in TOP (windows)

For a project, I have to make a movement detector with NDI IN TOP in TouchDesigner. The problem: there are no source names. What should I do? (I use windows computer). I tried to download the NDI tools and followed the tutorials. Still no result.

The first step to debugging this would be to install the NDI Tools from the NDI website. Does your source show up in the NDI Viewer tool there on the same machine?

Yes, but in TouchDesigner, the NDI in is not showing what the webcam sees. It’s just the QR-code of NDI.
