I just upgraded a machine today and it has been disabled, and when I try to reinstall it, it says that it won't work on this version of Windows 10. Classic Shell is still working on prior upgrades...

I wouldn't be here if it worked. I've used windows for 20 years. This thing has bugs. I know what two windows on a desktop looks like.

I have two windows 10 computers, same version, same build. It works correctly on one and not the other. I still haven't found out why. Ironically, it doesn't work on the machine where I need it...

I have the current codec pack, and I can play all videos, but the length of flv files still doesn't show up in window's explorer. It does on other versions of windows.

It only shows the length of mp4, mpg, and wmv files.
