I apologise for answering late. The reason was, I downloaded a complete second installation of XP11.05r2, directly on the desktop, with complete global scenery. This took 2 days.
I used an installer created 2nd November 2017. The one I downloaded today is OLDER, from 31th October 2017. Results are the same:
The installed scenery files look good, and after first tests, files missing before appeared in XP. But it will take time to verify this in various areas of the world
I would like to add the installer logs of both installer versions, which both ended with the same error message. But I see no option to upload files. So here are the final lines. Let me know if you need more!
