How to open This project off github

Well I Found This Project Thing Is If You Click The Forum Page {the first link in the page } He Says That He Need Github LFS Which I Have And Also Engine version that he used is 4.11.2-release branch on github which i dont know how to download and he also said “rebuild the editor and fix externals before you procceed” I Also Got No Idea How To Do I Am An UE4 Noobie So I Am Sorry If it seemed a bit newbish :] thanks folks.

The process is a bit complex. I have not used GIT LFS but I will try to give you some ideas here. So in your epic games account you need to choose the option that says link to github and you will get an email inviting you to the source code repository on Github. Once invited you will be able to download the source versions found on there. I would put it in a special folder and keep it apart from the unreal binaries you may have. For instance in the documents make an UnrealSource folder. That way its near your UnrealProjects folder and keeps everything organized.
Then download that project you want and when you go into it you will have a .uproj file. Double click on that and it will ask which engine version to use, do not chose any of the binary releases like 4.11 or 4.12 instead you need to navigate to the UnrealSource folder I suggested to make or name it anything you want really just make sure you can easily find it. So go into that folder and just highlight the engine folder, dont go into it or choose anything in it just click once on it and choose ok. What this does is points the .uproj to that source engine and it will generate the files and build the project to play around with. It will appear in your launcher for use, so thats handy.
I think thats it. Let me know if you get into problems.

I am sorry I forgot to tell you how to build the source engine. Here is a link to the documentation on how to do that
.https://docs.unrealengine./latest/INT/Programming/Development/BuildingUnrealEngine/

So Basically I Dont Have To Download UE 4.11.2 Release Branch To Play it At All ??

Yes you do have to if that is what the project was built off of. It is possible, maaaaaayyybe to open it with a binary release but some things may break. If you attempt to open it with your 4.11 and something bad happens you will need to delete the saved, intermediate and derived data cache folders in the project and then follow the steps mentioned above.

When I looked at the files on github it said the engine version needed was 4.9
=) welcome to the wonderful world of game dev. I don’t know if this project was what you wanted because you liked the game or just wanted to see something built but I liked a project someone uploaded that was based of one of the witcher games. http://krzysztofteper./korath.html
You need to go all the way to the bottom and sign up for the website that hosts the files to get the scene.

also i got an error the selected directory is not a vaild engine installation

ugh this is taking a south turn real quick

ya i actually wana see some stuff and know he made them but problem is i got this message Setting up Unreal Engine 4 project files…

GenerateProjectFiles ERROR: We couldn’t find a valid installation of Visual Studio. This program requires either Visual Studio 2013 or Visual Studio 2012. Please check that you have Visual Studio installed, then verify that the HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Microsoft\VisualStudio\12.0\InstallDir (or HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\VisualStudio\12.0\InstallDir on 32-bit machines) registry value is set. Visual Studio configures this value when it is installed, and this program expects it to be set to the '\Common7\IDE' sub-folder under a valid Visual Studio installation directory.

Press any key to continue . .

Now What !?!?!?!?!?! Also Dosent Games Require That Stuff ?? So I Am Histatnt About Deleting It

Ahh, i see. You will need VS 2012 to compile the engine. When you use the binary version of unreal the engine is pre-compiled. To run source version of engine you need VS to compile it.

But will it conflict with each other ??? Am i forced to uninstall 2015 visual studio cuz alot the games i play on my pc need that
