Hmmm. I have my MSFS install in a non standard location. However there is a C: Program Data file that installs with the TDS software.
Do you have this folder? C:\ProgramData\TDS\GTNXi\FlightSimEXE - >5 files in there?
And this one? MSFS directory\Community\tds-gtnxi-gauge\Gauge -> is there a .wasm file in there?
Also, can you run the TDS GTN standalone? (IE not going in the sim)
If you have all that - this might seem weird....but once you load into the sim and see no GTN in your arrow.... try exiting back to main menu, and load the flight again on the runway.
