How to Fix “Failed to load library” in Roblox

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

Roblox might fail to load a couple of libraries.

They are SensApi.dll and OpenGL32.dll, both of them are dynamic link libraries.

SensApi.dll is a system file that helps to monitor the hardware of the system and software resources.

The resources are CPU usage, memory usage, and disk usage.

Alternatively, OpenGL32.dll communicates with the GPU in order to render 2D and 3D graphics on a computer screen.

In some cases, these files may not be available or corrupted which can stop Roblox from launching.

Why did Roblox fail to load the library?

The most common files include SensApi.dll, OpenGL32.dll, and MfPlat.dll.

These files are essential for the Windows operating system.

If they are corrupted, old, or missing, Roblox will not be able to launch.
