Hi again Matt
I'm no expert when it comes to reading log reports, but the first thing I noticed is that your copy of X-Plane 11 is in the following directory path:- C:\Users/McBride/Desktop/X-Plane 11/
I believe it is recommended to have your X-Plane 11 folders/files placed directly in the root of your C: Drive, the directory path of which will then look like this:- C:\X-Plane 11\, in File or Windows Explorer (depending on what OS you're using?)
I guess that your X-Plane 11 Installer application will also be located in C:\Users/McBride/Desktop/X-Plane 11/, when it too should be in C:\X-Plane 11\
Try moving your entire X-Plane 11 folder and all associated files directly into your C:Drive and then re-try the Installer application.
