GTNXi Blank Screen after Windows 11 Upgrade

[millingp]

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

Paul
