OpenGL 4.6 is the final major OpenGL release before Vulkan took over. No "OpenGL 4.7" exists.

OpenGL 4.6 is not a standalone software you download; it is a included directly with your graphics card's drivers. To "download" or update to OpenGL 4.6, you must install the latest drivers from your hardware manufacturer. 1. Check Your Current Version

VirtualBox, VMware, and Remote Desktop often use software rendering (LLVMpipe or Microsoft Basic Render Driver) which only supports OpenGL 2.1 or 3.0. Hardware-accelerated OpenGL 4.6 requires direct GPU access.

After installing the new driver, confirm you have OpenGL 4.6.
