it wont work, it says that i need "OpenAL32.dll'

first, that is not in any of the files and it is also impossible to open a dll file. How do you open a dll file?

Hey there! For some reason the file is not installed on your computer. OpenAL is a file that allows things to play music & sounds. You can get it from here. Choose the installer on this page: https://www.openal.org/downloads/

OK thanks, so, i have downloaded it and i have it installed, what do I do next. Should I insert it into a certain file? Please let me know.
