Hiya. Been a while.
Because yt-dlp GUI is installed in Program Files by default, yt-dlp needs admin perms to update itself. Something I haven't considered while writing this program, or the installer script for that matter, until just the other day.
This update should finally allow you to actually use the integrated yt-dlp updater. The setup also includes updated binaries for yt-dlp, FFmpeg and .NET Desktop 8.
