Generate project files issue

So yesterday i downloaded the source code for ue4 to do some coding and i cant seem to be able to generate project files?

I get:

C:\Program Files (x86)\MSBuild\12.0\bin\Microsoft.Common.CurrentVersion.targets
(3606,5): error MSB3030: Could not copy the file "obj\Development\UnrealBuildTo
ol.exe" because it was not found. [C:\Users\QWER\Desktop\UnrealEngine-4.2.1-rel
GenerateProjectFiles ERROR: UnrealBuildTool failed to compile.

Press any key to continue . . .

Do you mind helping a guy out? :frowning:
I have been downloading it from github and by zip, got dependencies and still nothing.

Hi Illusive_S,

Could you please make this a post on the answerhub at in the Installation and Setup section? Thank you!
