Problem installing X-Plane 11 on PC with Windows 10

Question

When I attempt to load X-Plane 11 the installation stops shortly with the message 'Permission denied. Perhaps you do not have access to a directory or file system'.  I am logged on as administrator.

Answer 1

Where did you install X-Plane?

Comments

I installed it on the desktop.

Can you try and launch the installer again, so that every file can be checked and repaired if needed?

If no luck, please include the log.txt file found in X-Plane 11 folder.
