Vscode-cpptools: cannot open source file "corecrt.h" (dependency of "iostream")

[Hanano-Yuuki]

* Operating System and version: windows10-1709
* VS Code version:1.18.0
* C/C++ extension version:0.14.2
today when I open vscode to edit my code it suggests me "cannot open source file "corecrt.h" (dependency of "iostream")"
but it worked well yesterday.
after I change the C_Cpp.intelliSenseEngine setting to Tag Parser.the problems disappear,but itelliSense cannot works as conveniently as my original settings(C_Cpp.intelliSenseEngine:Default)
using VS2015/VC/include or using MinGW/include are the same situation...
I wonder if I forget to add something into c_cpp_properties.json 
maybe this is not my fault because vsc worked well yesterday and the program can be run sucessfully

and this is my c_cpp_properties.json now:

{
"name": "Win32",
"includePath": [
"C:/VS2015/VC/include/",
"C:/VS2015/VC/atlmfc/include/",
"C:/Program Files (x86)/Windows Kits/8.1/Include/um",
"C:/Program Files (x86)/Windows Kits/8.1/Include/shared",
"C:/Program Files (x86)/Windows Kits/8.1/Include/winrt",
"${workspaceRoot}"
],
"defines": [
"_DEBUG",
"UNICODE"
],
"intelliSenseMode": "msvc-x64",
"browse": {
"path": [
"C:/VS2015/VC/include/",
"C:/VS2015/VC/atlmfc/include/",
"C:/Program Files (x86)/Windows Kits/8.1/Include/um",
"C:/Program Files (x86)/Windows Kits/8.1/Include/shared",
"C:/Program Files (x86)/Windows Kits/8.1/Include/winrt",
"${workspaceRoot}"
],
"limitSymbolsToIncludedHeaders": true,
"databaseFilename": ""
}
}

@Hanano-Yuuki ,hello , how did you solve this problem at last , I just have the same problem!

[Hanano-Yuuki]

@Zeta-lime I think it may help you:
https://github.com/Microsoft/vscode-cpptools/blob/master/Documentation/LanguageServer/MinGW.md

by the way,run g++ -Wp,-v -E -xc -x c++ NUL to see the include files(if you use G++)
and the order is important
hope it can help you

Thank you this is exactly answer I am seek for!

You fixed this problem by changing to gcc as the compiler...For someone choosing MSVC, I fixed the "cannot open source file "corecrt.h" (dependency of "iostream")" issue by changing the include path in _c_cpp_properties.json_

"D:/Program Files/Microsoft/MSVC2017/VC/Tools/MSVC/14.12.25827/include/*",
"C:/Program Files (x86)/Windows Kits/10/Include/10.0.10240.0/ucrt",
"C:/Program Files (x86)/Windows Kits/10/Lib/10.0.10240.0/ucrt/x64",

I installed MSVC on D: drive, you may change that according.

The last line does the job. You can omit the rest lines safely.
