openal32.dll
This file is not a system component: openal, supplied with the game or by creative. Restore it from the source that installed it rather than downloading a replacement.
Do not download this DLL on its own
Searching for a missing DLL by name leads to sites that hand you that single file. It is one of the oldest and most effective malware delivery methods there is, and a system DLL from an unknown source is indistinguishable from a deliberately modified one. There is never a legitimate reason to obtain a runtime component that way.
What it is
The OpenAL audio library, used by a number of games for positional sound. It is not a Windows component and is normally installed by the game itself, often through a redistributable in the game folder.
Where you see it: Games from the 2000s and 2010s, and some emulators.
Look for an OpenAL installer inside the game directory, commonly in a redist or _CommonRedist folder, and run it. Failing that, reinstall the game. OpenAL Soft is an open-source implementation many games work with, but obtain it from its own project rather than from a DLL site.
Why there is nothing to download here
There is no verified download we can offer for this one, because installing a file is not the fix. The steps above are what actually resolves it. That distinction matters: the sites ranking for this file name are selling a download that would not have helped even if it were safe.
