Error Entitled, "OpenAL32.dll is missing"

I downloaded the WC Saga game, the installation was good but while launching the game, I am confronted with the above error message. I tried re-installing two to three times but getting the same error. Though OpenAL32.dll is already present in the installation folder. I am running it on my Windows 10. Also from the online search, I came to know about the DLL site where I downloaded the latest version of OpenAL32.dll from here: dlldownloads.com/openal32-dll/ . But it also didn't solve my issue. Please provide some suggestions regarding this topic. Thank you.
