When I do a clean install of X.plane11 it runs fine. Updating from v. 11 ruins my installation. The installer tells me, that permission to files is denied, and that there is an empty file, that I can not find anywhere,
Log files are here, the problem have been there at least the last month, where I have tried to find a solution. I am logged in as administrator and the installer is run as administrator. The problem may be in windows 10, but I could not find a solution.
Apparently no one else has the problem, on the Avsim and xplane.org forums nothing has been mentioned, therefore I will try here
