Org.lwjgl.LWJGLException: Could not locate OpenAL library error again

I assume you are bundling the openal32.dll with your app?

Yes it's in it's own dir, together with the other DLLS

I have seen similar problems when you have some other audio application running. OpenAL fails to open the device, and fails miserably.

Ok I had just installed XP and sound card wasnt installed properly 

It works now.

Still it shouldnt crash like that or what ?
