I’m trying to configure/run Pulse using the instructions posted here: [https://gitlab.kitware.com/physiology/engine/-/wikis/Using%20MSVC](https://gitlab.kitware.com/physiology/engine/-/wikis/Using%20MSVC) but I keep getting a strange error:
the source folder contains all the files from the latest Pulse release. I’ve tried using older versions of both cmake and Visual Studios but I get the same result. Any tips?

Do you have a CMake log?
Did you just download and install Visual Studio?
One mistake that I sometimes see, is that when you install Visual Studio, by default, C++ support is not installed. You have to manually enable it in the installer to get the C/C++ compiler installed (By default C# is expected to be used)
Once you hit `Configure` on the CMake GUI, you should get log messages about the compiler you have chosen. This is what I get:
The C compiler identification is MSVC 19.24.28315.0
The CXX compiler identification is MSVC 19.24.28315.0

Okay, I manually enabled C/C++ (or at least I think I did). Now I get this message in the log window:

The CXX compiler identification is unknown

Hmm. It still seems that the compiler is not configured right.
Here is my C++ settings

You might want to try fully closing CMake and opening it again, and maybe also rebooting your machine when you are sure you have C++ support in Visual Studio

It works now! Not entirely sure what I did but thank you so much!

Great!
You also might have deleted your CMakeCache.txt located in the build directory, so CMake will start fresh and look for the compile a new.
Let us know if you have any other questions or cool applications with Pulse!
Thanks!
