When I install and run it on my new one with Vista, I get the error message I copied above. What can I do? I changed all the compatibility settings, but nothing would even open it. Thanks.

Hi,

the vertex_array is no longer an extention , the new OpenGL library support the API

natively , so you can't run it since the API as changed

I am afraid that there is no solution , try and OLD Opengl32.dll

or a patch of your old game .

I'm afraid I have no idea what you're talking about when you said, 'Opengl32.dll.' What / how do I do that?   It's Frog Frenzy 2 by Cosmi that I'm trying to get working. The first Frog Frenzy works fine with the compatibility adjustments, but #2 doesn't work. If the older one works, I find it hard to believe that the newer one wouldn't.   I didn't see any patches on Cosmi's site.   Thanks.

I would try to explain , as simple as I can : the OpenGL32.dll is the API library of OpenGL on Windows it's a stub witch call an ICD Driver that relay the fonction to the Graphic board the OpenGL32.dll is part of system installation the ICD driver is part of Graphic board driver installation.   OpenGL as many release from 1.0 to 2.0 the transition to new functionality is made by adding some Extention fucntion for example GL_EXT_vertex_array when the extention is approved the function API change to glVertexArray the only way to make the application run is to recompile it with the change   you may change setting of your game to use DirectX instead of OpenGL is has better compatibility   Hope this help
