Here is a copy of my log.txt x-plane file after crashing with latest update
I don't know if this is the right answer, but this is what I've found with Beta updates. When you run the installer, it creates a new X-plane application in your directory. You have to make sure you use the newest version to run XP 11. I always delete the "older" file and use the newest one.
The installer should not be creating a new, duplicate executable in your folder. If it is, and you are using the latest version--4.01r1--please file a bug report with more details!
