Automatic start of GTNXi when MSFS starts

[Raller]

Hello everyone,
I don't know how I managed it, but for quite a while GTNXi started automatically when I started MSFS.

After I reinstalled MSFS because I switched to a larger SSD, GTNXi no longer starts automatically.

What do I have to do to get GTNXi to start automatically again along with MSFS?

Thanks in advance
