Hi again
I've had a look through your X-Plane Installer Log.txt file and have noticed that when the installation begins, it starts deleting files in your C:\X-Plane 11\Resources\default data\CIFP\ folder, namely:-
0:12:37.157 I/INS: Deleting file C:\Users/user/Desktop/X-Plane 11/Resources/default data/CIFP/CTK2.dat:
0:12:37.157 I/INS: Deleting file C:\Users/user/Desktop/X-Plane 11/Resources/default data/CIFP/DITB.dat:
0:12:37.157 I/INS: Deleting file C:\Users/user/Desktop/X-Plane 11/Resources/default data/CIFP/EKVA.dat:
0:12:37.157 I/INS: Deleting file C:\Users/user/Desktop/X-Plane 11/Resources/default data/CIFP/ENNK.dat:
0:12:37.157 I/INS: Deleting file C:\Users/user/Desktop/X-Plane 11/Resources/default data/CIFP/FDBS.dat:
0:12:37.157 I/INS: Deleting file C:\Users/user/Desktop/X-Plane 11/Resources/default data/CIFP/FDNG.dat:
When the install gets to this point, the file stops logging entirely?
All of the highlighted items in red, are ICAO airport codes which do not appear to be valid any longer according to the latest AIRAC cycle in Navigraph. I did however find five of them in Skyvector and all are very minor airfields dotted around the world, but probably now defunct?
This is probably why the X-Plane 11 install is trying to delete.
To get around this, you may wish to consider deleting your C:\X-Plane 11\Resources\default data\CIFP folder entirely and allow the X-Plane Installer to replace any missing or corrupt files as necessary.
Hope this helps:-)
Regards
