I have tested the AppVeyor release build for the attached branch on Windows 10. The installer had to be run as administrator when installed into C:\Program Files, the game can then be run without admin privileges. stdout.txt is written to C:\Users\<username>\.widelands
Also, the uninstaller can remove the Widelands directory cleanly now, because there is no new file written into it.
