I just installed the 1.6.3 build of RetroArch (via replacing the 1.6.0 exe files for RetroArch and RetroArch Debug with the appropriate 1.6.3 files), and whenever I try to open the application I get an error message reading “The program can’t start because libass-9.dll is missing from your computer. Try reinstalling the program to fix this problem.” What exactly is “libass-9.dll”, where can I find it, and how do I properly install it?
EDIT: Forgot to mention that I’m using Windows 10.
