No, the first PC I attempted to set it up on was a laptop and I diagnosed the OpenGL issue there first. I then attempted to setup on another, more capable PC with a more capable GPU. After getting identical results with this PC I discovered the GPU had never been properly installed with the correct driver and was using a native windows 10 driver which worked to all intents and purposes ( I didn’t even think to examine the device settings) but crucially did not support OpenGL 1.5 hence my issue. I guess you cannot assume anything with Hardware and Software combinations !

Ok, I have now resolved my issue and the GTN 750 is now showing. Turns out that my PC was not using the Installed Graphics Card drivers but a Windows 10 native driver. This was not apparent until i changed the debugger to LogTrainer= 1 which then showed the problem with loading was due to OPENGL 1.5 not being available. I then downloaded the latest drivers for the Graphics card and everything sprang to life. For Clarity I should say i was using Garmin Trainer V2.7.1.0 and GTN Trainer V6.62.4 and loaded these before installing RealityXP although relieved to have found a solution and looking forward to using the software I do feel the level of support from realityXP is somewhat lacking. Thanks to all for the suggestions.

fppilot, Seriously, yes, I worked through all of those topics without yielding an answer. Fair enough ? Bert, I did not see that particular file in the exclusion list but will check. Thank you.

Have attempted to research this issue through this forum and have drawn a blank so far. I have installed Garmin Trainer 6.21 and this works separately. Windows 10.
