Load order for DLLs

[Capypara]

Hi! I'm having an issue where PyInstaller frozen libraries search the Windows PATH BEFORE the directory of the frozen app. This leads to issues, because I bundle Gtk and some libs and users have reported issues because of other programs they have installed.

How do I get PyInstaller to load the DLLs from the app's directory first instead of the PATH?

Here's the error message as reported by one user:

FAHClient in this case is some other app, not mine. It's in the PATH of the user.
