Michael from Teaching Tech made a video guide about the installation. He was so kind to allow me to embed it here! Thumbnail installation starts at 1:49.

Dark background on some thumbnails

a folder with two thumbnails whose background is entirely black

Clear your Explorer thumbnail cache (see above) or copy the file to a different location.

This is a bug in Windows 10 that also affects other thumbnails – for example transparent PNG images here and here.

I can’t do anything in my program to work around it, I’m afraid. Please use the Windows 10 feedback function to report this to Microsoft. If enough users do it, they may eventually fix it. Windows 7 does not have this bug.
