What is 0xc000007b?

0xc000007b shows up as a high-severity software runtime fault. An application built for a 64-bit architecture tries to load a 32-bit library (or vice versa). It's most often caused by confusion in System32 and SysWOW64 folders (mixed DLLs) and corrupt DirectX/VC++ installation. See the troubleshooting steps below for the fix.
