How to check if I have openAL on my windows

[Carlos Menem]

I want to install unknown horizons but the game comes with this thing called openAL and is asking me if I have it already as to not to reinstall it, I have the game hanged because I dont know how to check if is installed on my windows, is there a way to check this? it says it needs it to play audio and music..

It should be shown in the Add/Remove Programs menu in control panel if you have it installed. If you can't find it or don't remember if you installed OpenAL somewhere in the past, just go ahead and re-install it, it won't have any bad affect.
Good luck.
