Error building from source

I am trying to build the 4.0.1 build from github with MSVS Express 2013 and have the DX2010 runtime installed.
When i try to build i get these errors after about 15 seconds



Error	1	error : System.OutOfMemoryException: Insufficient memory to continue the execution of the program.	E:\UE4\UnrealEngine\Engine\Intermediate\ProjectFiles\EXEC	UE4
Error	2	error : UnrealHeaderTool failed for target 'UE4Editor' (platform: Win64, module info: E:\UE4\UnrealEngine\Engine\Intermediate\Build\Win64\UE4Editor\Development\UnrealHeaderTool.manifest).	E:\UE4\UnrealEngine\Engine\Intermediate\ProjectFiles\EXEC	UE4
Error	3	error MSB3073: The command "..\..\Build\BatchFiles\Build.bat UE4Editor Win64 Development" exited with code -1.	C:\Program Files (x86)\MSBuild\Microsoft.Cpp\v4.0\V120\Microsoft.MakeFile.Targets	38	5	UE4

I am running on a 16Gig PC with about 11Gig free before trying to build, So i dont know what is going on there.
As for error 2 and 3 i have no idea.

VS Output.
