Error While Installing UE4 Through The Source Code

Hey Guys, so I got this error when trying to build UE4 from Visual Studio/Source File (right-clicking on UE4 and choosing “Build”) where it said something like “…..\Build\BatchFiles\Build.bat UE4 Editor Win64 Development -waitmutex1 exited with code -1”.

I’m pretty sure I followed the instructions correctly given in the source file. I’ve also searched on the answer hub but haven’t got a solution to fixing this problem.

My Specs are :
Windows 8.1 64Bit
AMD Radeon R9280
…and I don’t really know what else to put in :stuck_out_tongue:

Hey -
