That feature should be ignored unless you have specific reasons to use it.
Can anyone else confirm this? I deliberately changed the extension on all bundled executables to .--- because they aren't meant to be run directly, and under normal circumstances this does not affect functionality.
As a workaround, you can try renaming them back to .exe and editing the batch files accordingly. Make sure to either use Notepad or select cp437 encoding in your text editor.
