Microsoft Windows issues

Can't locate data files - first time install

Note  Default locations of $FG_ROOT, is the path of your installation directory. Examples are here $FG_ROOT. If you changed your installation directory during install of FlightGear then use that path instead

After a first time install and upon running FlightGear for the first time you see this dialog

Resolution - Tell FlightGear where to find the data files that were installed. I present here 3 options. Whichever you choose, make sure you update the PATH according to your installation directory

• Choose Folder and point it to $FG_ROOT
• Paste these 3 lines inside of Notepad.exe, or some other editor, save as fg-root.reg file to desktop, then double click the file and add the entry to registry

Note  Yes, you need the double \\ in the path

Windows Registry Editor Version 5.00 
[HKEY_CURRENT_USER\SOFTWARE\FlightGear\FlightGear]
"fg-root"="C:\\Program Files\\FlightGear 2016.1.1\\data"

• Open up regedit and add fg-root Key as a string value of $FG_ROOT

Terrasync - Known Issues

Failed to remove file

file remove failed: (./.terrasync_cache) reason: Permission denied

TerraSync cache files can not be deleted. You will see errors in console like above. There is not much to do other then delete the .terrasync_cache files manually and then run FlightGear again.

Resolution

Note  Not recommended. Understand the consequences
