HELP! - Pointing to cl.exe with Visual Studio 2017

So I recently started using UE4, and am trying to make a C++ game. I have Visual Studio 2017, and am aware of the location of cl.exe (I actually have 4 of them):

"D:\Program Files (x86)\Microsoft Visual Studio\2017\Community\VC\Tools\MSVC\14.11.25503\bin\Hostx[64 or 86]\x[64 or 86]\cl.exe".  

So I go into regedit to change the location to

"D:\Program Files (x86)\Microsoft Visual Studio\2017\Community\VC\Tools\MSVC\14.11.25503\bin\Hostx64\x64".  

However, Unreal Engine, obviously, cannot find cl.exe at that path + “\bin\cl.exe”

So my question is the following: which of the 4 cl.exes do I use for Unreal Engine, and is there a way to stop Unreal from adding “\bin” to the path, or should I rename the folder (probably a bad idea).

Thanks in advance.

No one can has an answer for this.
