Hi,

I purchased and installed the GTN 650 and 750 this week.  The plugins menu in XP has an entry tor Reality XP and options to select GTN1 or GTN2.  From the default 172 I used the plugins menu to add the 750 to this aircraft.  It's there, but not powered up.  Power option in the setup menu is Auto.

From searching this forum, I discovered the un-powered state can be caused by not having the trainers installed.  I was not prompted to install the trainers during installation and I presumed the reason is I have an up-to-date installation of the "other" GTN product installed on this machine.  Version 6.62.4.0 of the GTN trainer is installed in its default location at C:\Program Files (x86)\Garmin\Trainers\Packages\GTN.

I've checked my antivirus software for quarantined *rxp* files, and there were none flagged during installation.

I an running Windows 10 Pro, version 1909, and for graphics two NVIDIA 1080 in SLI configuration.  I read about forcing the app GTN Simulator.exe to use a dedicated graphics card rather than onboard graphics.  In my NVIDIA control panel, there is no option in the Desktop menu that allows setting "Run with graphics processor" to the context menu.  So I haven't been able to test that.

Time for some help from the experts!  Hopefully the log files will be helpful to you.  Apparently it's not possible to attach a file in this forum?  So I'll paste the contents of both log files.

Thanks for your help!

Hi,

Searching this forum with "hwm_eeprom_win32":

or

plenty to choose from.

TL;DR: Windows ACL and admin rights locking you out of your files.

Hi Jean-Luc,

Thanks for your assistance with this.  It is possible I installed the trainers with admin rights.  The post where  you solved the problem was an interesting read!  I ran X-plane as administrator and the GTN powered up in the 172.  I quit and re-ran without admin rights and it worked too, just as your post stated.

I didn't think to check the sys_nandi permissions before running X-Plane as admin, but when I checked it after doing so, the username line was not there.  Nonetheless, the problem seems solved, so the self-healing step worked.

You also just taught me to use error information from the log file as a key for searching--something I had n ot thought to do.  Thank you!

Larry

I'm glad you've sorted this one out and I sincerely appreciate your take on my comments!

Many people are jumping their guns lately when the only answer I sometime give is "search the forum" "search google" etc...  I know the confinement and situation is really affecting a lot of us, me too, and you can find some of my answers a little "blunt" lately (I'm working on it).

The truth of the matter is that I know pretty much what are the issues our customers are encountering day to day, and I also know there is already an answer in our forums, not just because I assume it is so with more than 19000 messages in the RXP support forum, but because I just remember most of them.

We've also refined the log file content thanks to our customer feedback over the years in trying to output the most relevant data for the most occurring issues (like the expected path to the "flight plans" for the import feature if it is not found).

This really is a helper both for us but more importantly for you, our customers.
