When I tried to update the Open Broadcaster Software(OBS) it prompted an error box telling “Update Failed: GraphicsCaptureHook.dll is still in use. Close all programs and try again”? How to resolve this obs graphics capture dll error?
Resolve Obs Graphics Capture Hook Dll Error
Looks like the DLL file of your program is being locked or being used by another program.
The first thing to do is to restart your computer and then, start the Open Broadcaster Software again and start updating it. This procedure should fix the problem.
You can download the latest version from here.
