Hi Kash4,
I am not with Laminar Research; just a flight simmer.
I have noticed what appears to be a few issues for me having looked at your Log.txt file. I normally have problems with the interpretations but this one gives me 3 clear messages.
1. Download and upgrade the drivers for your graphics card. The card appears to me to be aged. Does it meet the specifications as detailed here at https://www.x-plane.com/kb/x-plane-11-system-requirements/ Consider the "recommended specifications" particularly the VRAM. My original GPU was a GTX 780 unit with 3Gb of VRAM and I have now upgraded to a GTX 1080 on my Main XP PC. You may consider an upgrade but try the driver upgrade first.
2. Have you created a sub-directory called "games" on your desktop whereby you have then installed X-Plane into that sub-directory? If you have, I would strongly suggest you delete X-Plane from that directory and place it directly on the desktop as Laminar Research suggests or create a newly dedicated sub-directory on your your "C" drive as "C:\x-plane\" A better and safer option is to have an additional dedicated drive just for x-plane over and above what is on your PC. In performing a fresh install on my desktop I did not get the "games" sub-directory as you have.
3. You have been advised in your screen message that the "plug-in " is causing your problem. In looking at your log.txt file it clearly states the plug-in file X-Life is causing your crash. I strongly suggest you completely remove this plugin and try and run X-Plane without it. If X-Plane then runs you need to decide what you then do with it.
Good luck.
Glenn
