I was having issues compiling the Windows Universal Platform version of the Unreal Game Engine.

I kept getting ‘/FU’ requires an argument, and would fail compiling.

After lots of troubleshooting, it turns out that I just need to downgrade my Windows 10 SDK to versionĀ 10.0.14393.795.

Here is a list of all the current versions of the SDK.
