Describe the bug
The preference 'Set the video's thumnail as album art (for mp3 only)' doesn't work correctly.

Steps to reproduce the behavior:

1. Go to 'https://github.com/moshfeu/y2mp3/releases/tag/v2.5.4'

3. Start the download

4. Execute/Double-Click the program 'y2mp3.Setup.2.5.4.exe'

5. Wait until the installation has completed

6. Start 'y2mp3.exe' (only if not automatically after step 5)

Not asap after all, sorry..
If I'll have time in the future, I might get into it
Meantime if someone wants to fix it, I'll be more than happy
