How to Fix “Failed to load library” in Roblox

Are you getting a “Failed to load library” error in Roblox?

There are a couple of libraries that Roblox might fail to load.

This includes SensApi.dll and OpenGL32.dll, which are both dynamic link libraries.

SensApi.dll is a system file that supports functions related to monitoring the system’s hardware and software resources.

This includes CPU usage, memory usage, and disk usage.

On the other hand, OpenGL32.dll communicates with the GPU to render 2D and 3D graphics on a computer screen.

In some cases, these files may be corrupted or missing, which prevents Roblox from launching.
