This did not reproduce with Microsoft Visual Studio version 15.6.2 at the same CL in //UE/Main. Only occurred after I updated from 15.6.2 to 15.7.1.

Steps to Reproduce

Have Visual Studio 2017 version 15.7.1 on your machine


  1. Create a code first person template project
  2. In VS2017, build the project's editor
  3. Open the project in the editor
  4. Package a development build of the project for the Win32 platform

Project fails during the build phase with multiple errors similar to

ATHelper: Packaging (Windows (32-bit)):   Error executing C:\Program Files (x86)\Microsoft Visual Studio\2017\Professional\VC\Tools\MSVC\14.14.26428\bin\HostX64\x86\cl.exe (tool returned code: 2)
UATHelper: Packaging (Windows (32-bit)):   PCH.CoreUObject.cpp
UATHelper: Packaging (Windows (32-bit)):   c1xx: fatal error C1356: unable to find mspdbcore.dll

Project packages a Win32 development build successfully
