Can't start UE4

Getting Started & Setup

I can use the Unreal Launcher just fine, but I can’t start Unreal Engine 4, be it through the launcher or directly from the directory. I get the error code 0xc000007b, which is a windows error code, but no fix has helped. This happens ONLY with UE4 and no other program whatsoever. How can I get it to run?

Things I’ve tried include reinstalling everything after complete uninstall and registry key wipe, checkdisk, reinstalling/updating Visual Studio libraries/DirectX/GPU and CPU drivers/etc. and generally every other “fix” I’ve found for the issue but it’s still there. If it’s relevant any, the troubleshoot option in the ULauncher doesn’t recognize my CPU’s cores for some reason, saying it has less that 4 when it has 6.

My computer’s specs that could be related to the issue are:
AMD-FX6350 CPU
Sapphire AMD Radeon 265X 4GB
4GB DDR3 1800MHz RAM (I have 90% of it available when trying to run UE4, so I doubt it’s an issue there)

Any help is appreciated.

EDIT: Forgot to include the OS, it’s Win 7 Professional x64.
