So I want to edit Hello Neighbor Alpha 2 and I extracted the files from the Pak. Im using UE4.12.5 but when i try to open the Project, this pops up: The following modules are missing or built with another different engine version: UE4Editor-HelloNeighborReborn.dll Would you like to rebuild them now? I clicked yes but this pops up: “HelloNeighborReborn could not be compiled. Try rebuilding from source manually.” I have been trying so hard to open the project, but I can’t find any way how to open it in Unreal Engine. I did not create the project obviously, so I can’t open it in the editor. I also tried opening it in Visual Studio 2013, but it says it’s missing source code. It says: This project does not have any source code. You need to add C++ source files from the Editor before you can generate project files. I can’t open it up in the editor. I can’t find anywhere that tells me how to fix this problem. I am a newbie at Unreal Engine but I really want to open the game up to modify the build. Please let me know if this is solvable.
