getting > 260 path length errors when executing start.bat ,and also GenerateProjectFiles.bat leading to install errors. I was also getting that in winrar but updated it and it worked fine thereafter. I’m guessing but maybe something probably needs updating on my windows 7 but I don’t know what (my windows is up to date with all latest ‘required’ patches).
Could you be a bit more specific in what the problem is (pictures might help)? It sounds like where you’re running Setup.bat (rather than start.bat, correct?) you’re getting an error that the path is too long? If this is the case if you move the folder where you’re running Setup.bat from to another path on your computer such as C:\Unreal\4.8\ (made up location and assuming Setup.bat is inside the 4.8 folder).
