Dear friends, I have been a happy user of the RXP GTN750 for more than six months now. I use it with every flight. I am RXP dependent since I purchase their incledible addon last november. Everything perfect so far. But yesterday (may 24th, 2020) I was prompted to update my GTN750 to a new version (do not remember which, I only remember it was released in May). I accepted, why not. I just clicked ok and the installer did its things. Since then I can open my popup GTN but the screen is dead. Black. I searched for possible problems in the forum and read the users manual again. It seems that mine is not a rare issue.  The strange thing is that I have not changed anything in my rig: same pc, same components, same airplanes in P3D v4.5, and so on. I just clicked ok for an update and my RXP GTN simply stopped working.

I have tried all the solutions I am capable of: disabled antivirus, firewalls, etc. Reinstalled everything from scratch. Checked my log files as indicated in the users manual and in some posts in this forum. It reads a follows:

 

20/05/25 22:15:11.392 12272 -    ] # rxpGtnSim64.dll version 2.5.22.1

As the trainer appeared as NOT FOUND, well it must have been deleted somehow, I thought, so I decided to install it again. The installer says ALREADY INSTALLED IN MY HARD DRIVE. 

I give up. I do not know what to do next. I did everything that was in my hand. I need help now. Can any of you fellow simmers or devs show me some light of what is happening. I would appreciate a wise advice of what to do.

 

Thanks in advance,

Probably worth checking the trainer version - since the latest update doesn't support some versions the previous one did.

That's what caused that issue for me anyway!

Thanks Gazzareth for the reply. So let me try to get the whole picture. What I updated might not have been the RXP add-on but the Garmin Trainer? If it was the trainer, do you know if I can retrofit to my older version? I will focus on your approach and try to solve it till RXP comes with a feasible reason and solution. Hope they read my post and reply soon.

Thanks again.

Hi!

You have something wrong with the GTN and Garmin Trainer versions. The error log you provided says that you have GTN version 2.5.22.1 and Trainer version 6.62.0.

If you make an update, the current version of GTN should be 2.5.25 and the latest Trainer is version 6.62.3.

When you run the GTN update, there will be an option to update Trainer during the installation process. If everything is done correctly, the error will disappear and everything will work.

 

 

Thanks Nickbe. I will follow the instructions in the post you added. Sounds reasonable! I shall give it a try and let you know. 🤞

Just a question? Do you advise a clean install again or I could install on top?

Hi,

You can install on top first, and uninstall/reinstall only if it fails.

Will try later and will keep you informed. Thanks

 

Hi friends. Yep. Everything back to normal. You all were right. I had updated the GTN but not the trainer, so I tried to install on top without success because the installer said it was already in my hd. I just uninstalled both GTN and Trainer, searched for any files from any of them and deleted them. My advice, do not even keep the e-commerce application, cos it did not allow me access to the new versions. Just clean everything and start from scratch. 

I am now again a happy flier with my popup GTNs in the screens of my homecockpit!!!!

Thanks for your help. Hope to be useful to the community in the future in return.
