@LZR-Turner Don't download random dll files from the internet, that's not gonna work. binkw32.dll is part of bo2 so either: your bo2 game installation is missing files, in that case put piry.exe (https://piry.plutonium.pw/piry.exe) into your bo2 folder and run it. you didn't select the correct filepath to your bo2 installation in the launcher.
