GTNXi Blank Screen after Windows 11 Upgrade

[millingp]

Hi
I've been a very happy TDS GTNXi user.  Today I upgraded from Windows 10 to Windows 11.
Upgrade went well. But unfortunately GTNXi has a blank screen in both Black Square King Air and Milviz C310.

Offline GTNXi works ok though.

My Logfile shows the following error.....

Do an exception in windows defender

I use AVG, not Windows Defender.  An exception for what?

Hello Paul,

This is an issue with AVG antivirus conflicting with the TDS GTNXi, we describe this issue in the TDS GTNXi manual, the fix is very simple, you must set an exception for the gtn_simulator.exe full path:

C:\ProgramData\Garmin\Trainers\GTI\Production\GTI__GTN_Xi__20_20\app-20.20.13\bin\GTN_Simulator.exe

Additionally, you can temporarily turn off real time protection and you can confirm that the TDS GTNXi works fine.

Good luck and please let us know how it goes.

Many thanks for the prompt reply.  I set up an exception in AVG as suggested and that fixed the problem.

Thanks again
