If you have the FastSpring version and you agreed to the installer suggested installation directory typically c:\program files (x86)\DX10SceneryFixer then you may find that every time you launch DX10Controller that the C++ installer runs…
Sorry this is a mistake on my part – the C++ installer is meant to run just once, but because of the permissions Windows imposes on Program Files the market file cannot be deleted.
This problem does not occur with the Flight Sim Store version or if you selected a different installation directory.
If you are affected by this then open File explorer and find the DX10 Scenery Fixer directory and delete the file VC.txt shown highlighted below.
Alternatively download using your download link for an updated 2.8 that doesn’t have this issue – but its much easier to delete the VC.txt file as shown.
