Trouble getting TDS GTNXi to turn on in MSFS2024

[njline@verizon.net]

I am having a problem getting TDS GTNXi to turn on in MSFS2024.  

The TDS GTNXi shows up with a black screen in MSFS2024.  

I am using FlightSim Builder G1000nxi touch monitors.  The FlightSim Builder launcher app setup has a dropdown menu to select for use of TDS GTNXi but the unit does not show up on the G1000 touch panel as it should. This happens in MSFS2024 and Xplane 12.  

Any idea as to how I can get the TDS GTNNXi to turn on and work in MSFS2024 and Xplane 12?  
Is there a file there a file I must load in a community folder?  

Thanks

Hello,

We are sorry to hear of the issue, we are here to help.

As a first step in troubleshooting the issue, please try this:
With MSFS closed, start the TDS GTNXi Pro from the desktop shortcut and click on the GTN750Xi button. Does the screen light up?

Which antivirus are you using?

I attempted to upgrade my from basic TDS GTNXi to TDS GTNXi Pro.  After purchasing the Pro upgrade and engaging the executable file, the upgrade does not appear to have completed as I received an error message.  

"Error Installing: 
TDSGTNXiFlightSimEXE.exe
SimConnect.dll 
TDSGTNXiFlightSimManual.pdf"  

What must I do to get this to install properly and work?  

Just using the basic antivius app that comes with Windows 11. 

Thanks

I rebooted  reboot the PC, then re-ran the TDS GPS Manager as an admin (right click, select Run As Administrator)
Then attempt a reinstall/upgrade.  

The TDS GPS Manager - 1.0.1.7  displays the GTNXi Trainer is not installed.  It shows that Trainer Version 20.42.2 is available but when I click on "Download And Install", the file does not install and the page switches to "Please Select A Product to UNINSTALL".  I have tried to download the trainer through the TDS GPS Manager mulitple times without success.   

Version 3.12.1.0 Garmin Trainer Launcher already exists on my computer from a previous download but TDS GPS Manager is not communicating with it.  

I have attached a photograph of my TDS GPS Manager app.  

Is there a way to resolve this issue?  

Thanks

Hello,

We have answered your email requests sent both today as well as at the beginning of the week, but we did not hear back from you.
In this case, we strongly suggest checking your spam folder and letting us know here of the emails not being received.

Then attempt a reinstall/upgrade of only the TDS GTNXi Pro MSFS 2020/MSFS 2024. There is no need to reinstall/upgrade the PC Trainer until you have the latest TDS GTNXi Pro V1.3.1.2 installed.

Please follow only these exact instructions and get back to us, after upgrading the TDS GTNXi Pro and running it once, with a new log file from My Documents: TDSGTNXiExeLog.txt
