Hey M_ae-

Could you explain what you’re trying to do? If you are trying to compile the source version of the engine you should be able to do so simply by downloading the .zip file from GitHub and unzipping it to your computer. Then you can run the Setup.bat and GenerateProjectFiles.bat which will create the UE4 solution. Opening the .sln allows you to build the UE4 solution. Let me know if this is what you’re trying to accomplish or if you’re attempting to do something different.
