Before you click on any suspicious links promising an "OpenGL 1.5 installer," it is vital to understand how OpenGL works on Windows.

Modern drivers often emulate these old versions perfectly on Windows 10.

Since you cannot download OpenGL 1.5 directly, the solution to your error is to update your graphics driver to a version that supports it.

Help: Looking for "OpenGL 1.5 download" for Windows 10 – is that possible?

Has anyone successfully run an OpenGL 1.5–era app on Windows 10? Any other workarounds? Thanks.
