Hi jackg521
I'm not with Laminar Research, just a fellow simmer in the UK, but when I looked at your X-Plane 11 Log.txt, I noticed two things:-
1. At the start of the Log.txt file it states:- log.txt for X-Plane 11.05r2 (build 110501 64-bit) compiled on Aug 26 2017 10:24:51 X-Plane started on Mon Feb 4 15:35:48 2019. Which version of X-Plane are you trying to open?
2. The Log.txt file last entry was the successful loading of all 'OpenAL Extensions' and then it stopped, just before the next stage of loading all relevant Plugins?
How many versions of X-Plane do you have loaded on your PC, as you have referred to X-Plane 10 32bit & 64bit versions, with only the 32bit version able to function properly?
Lastly as far as the X-Plane Screen Res.prf file is concerned, I have not personally seen this in my Output/Preferences folder, but there has been a lot of discussion about it in the X-Plane.org Community Forum and there are also many suggestions that this file should be deleted?
Please click on following link that will take you to the relevant webpage:- https://forums.x-plane.org/index.php?/search/&q=screen%20res.prf
Regards and hope some of this helps
