Appdata crash when running a new version without running the executable first

[simon-riou]

When you run a new compiled version without running the executable from the installer first, it crashes since it tries to access the appdata directory which doesn't exist

It also creates the folder with an empty camera_configs directory.

This should be solved, either by looking in the local directory if none was found in AppData, or by propagating the files directly from the newly compiled version
