I'm a bit puzzled by this. When I open "Developer Command Prompt for VS 2022" from the Start menu, it sets the INCLUDE path appropriately. That entry in the Start menu was generated by the install of VS.

The premise of the problem is that you are required to both know of and to ensure the usage of the bat file(s) are applied to make ImportC work isn't acceptable.

Instead of dmd detecting it wasn't applied, and then applied automatically as part of running of the preprocessor.

It's a failure state built into ImportC on Windows. Alternatively, we could get MinGW working as per my email showing a way to make this work and not require this addition.

I don't really know how dmd can account for failure to install VisualStudio. The error message is coming from VS, not dmd.

Visual Studio is installed.

The PATH variables are not setup, and therefore it appears to the toolchain as though it hasn't been.

"x64 Native Tools Command Prompt for VS 2022.bat", basically dmd needs to detect that bat file and automatically apply it before calling the cpp.
