Intel Compiler uses wrong header files

Hi,

my Visual Studio is causing problems and I can't figure out what's going on. I am using Visual Studio 2017 and installed ICC18 and ICC19 including the IDE integration.

My project gets compiled with Intel Compiler 18.0.5.274 and Platform Toolset v141 but any translation unit fails to compile. To me it looks like ICC somehow picks up the MSVC header files. Does anyone know what could cause that?

Thanks!
