Retroarch missing dll files

So I just got a new tablet/pc and I was trying to get it set up. However, after downloading the latest version, retroarch said it was missing some dll files. I tried searching up the dll manually but I got stuck on avformat-56.dll and I can’t find it anywhere on the internet. Is there any big downloads or redistributable that I need for retroarch?

Sorry for any typos, I am typing on said tablet.

You need the redist file from here (on the bottom). Unzip it in your retroarch folder.

That’s for win64, check the other folders if you’re on a different OS.
