Sometimes the DLL is present, but the Windows components needed to read the DLL are missing.
In rare cases, a registry key mispoints to the wrong DLL location. Only attempt this if you are confident.
Win + R, type regedit, press Enter.HKEY_CURRENT_USER\Software\Valve\SteamSteamPath.C:\Program Files (x86)\Steam).// Supported Cameras
