I followed the document for linking vs 2017 with UE4 but it is giving me the same issue C:\Program Files (x86)\Microsoft Visual Studio\2017\Community\MSBuild\15.0\bin\Roslyn\Microsoft.CSharp.Core.targets(71,
5): error MSB6006: “csc.exe” exited with code -532462766. [C:\Users\tjsun\Documents\Unreal Projects\Engine\Source\Progr
ams\DotNETCommon\DotNETUtilities\DotNETUtilities.csproj]
also when I do setup.bat It doesn’t show the percent it does nothing then says and requests administrator for it then when I click yes it does nothing again what am I doing wrong?

Thats a windows specific limitation. Move your folder to something like C:/UE4Source/
That should fix the error.
ok I did that and the bat file on admin and setup worked I did admin for the GenerateProjectFiles and sorry if I am annoying you 
(PS: with that .net thing are you talking about the C++ with UE4 or something else. I have the UE4 C++ but still have the error do you know how to fix the .net problem? )
I have searched it up for hours but never found the exact answer the exact error is C:\Program Files (x86)\Microsoft Visual Studio\2017\Community\MSBuild\15.0\bin\Roslyn\Microsoft.CSharp.Core.targets(71,

GenerateProjectFiles ERROR: UnrealBuildTool failed to compile.
I fixed it apparently the problem was that I needed to repair the visual studio Thank you for you time and effort if I stumble across any other error can I ask you? Stay cool man! I felt like I was being annoying but you still were there for me so Thank You!
why does the initial build for source take forever? It has already taken two days and it’s not even half way
I have stumbled for weeks on the dedicated server and I got frustrated when I didn’t have the configuration settings “Development Server” “Development Client” “Shipping Server” and so on. So I manually made new configuration settings but when ever I used them they gave me (literally)hundreds of errors about not able to find specific path. So I looked on different forums and found out that they solved it by switching the version to the source. I did that then gave me the error “Missing C:/Users/tjsun/Documents/Unreal Projects/Engine/Binaries/DotNET/UnrealBuildTool.exe after build”. I check the path it gave me to find out that there was no “UnrealBuildTool.exe” I checked the GitHub to get just the “UnrealBuildTool.exe” but I searched the file and it wasn’t there, but switching to 4.16 still works. Is there another way to get the configurations? If anyone could help me I would greatly appreciate it.
Thank you very much for answering!!! but I do not have the Programs folder in my project
What are you using? Source or Launcher Version? And what are you trying to Build? Server Solutions are avaivable in Source.
There is already a big guide on how to Build a Dedicated Server on the Wiki you might want to look into.
That’s the thing I tried to switch to the source but it wont let me because I was missing the UnrealBuildTool.exe so right now launcher
That makes no Sense. You can Switch to source any time, it will update your Solution file and at that point you are on Source. Follow the Guide and you will be allright. Dont forget to Build your Engine Source and runt the Commands in the Source folder (also described in the guide aswell as on the git repo).
From the Screenshots you Posted I can Tell you did not Build the Engine at all.
Thank you and my GenerateProjectFiles.bat doesn’t work either it says csc.exe excited with code and by the way what is your profile picture
So why don´t you tell us this in the first place 
my Profile Picture is a Chibi Version of Ichigo from the Anime Bleach.
The error basicly means you didn´t install whats needed on your Windows machine. if you google up csc.exe error you will see it has something todo with .NET make sure you have it correctly installed with VS or by Hand.
Also make sure you run Setup.bat and everything in general with Admin rights.
Here a Link how to Setup VS 2017 with UE4
wait what do you mean Us? You seemed like a cool dude so I searched Nachtmahr in google and showed a band are you them? Was I talking to a band? 
=/ rightclick .bat → Run as Administrator
And please stop skipping Steps! You have todo everything in order. If one fails for some reasson you don´t even have to bother trying the next step.
