Tried to run GenerateProjectFiles.bat to build Unreal Engine from source ( link ), but got error like below: C:\>Users\x\UnrealEngine>GenerateProjectFiles.bat Setting up Unreal Engine 4 project files... GenerateProjectFiles ERROR: It looks like you're missing some files that are required in order to generate projects. Please check that you've downloaded and unpacked the engine source code, binaries, content and third-party dependencies before running this script. To fix, run setup.bat like: C:\Users\x\prj\UnrealEngine>setup.bat Note that you have to say no to the prompt Would you like to overwrite your changes (y/n)? .
