I am using a laptop with Windows 11 system, and I have made sure that I have installed all dependencies. However, I encountered the following error when using "Anaconda Powershell Prompt":

The default VS Studio generator is for VS 16. Are you running VS 17? You can specify that with the generator argument. (see http://hanspeterschaub.info/basilisk/Install/installBuild.html) If you downgrade to VS 16, I recommend deleting the .conan folder first from your home directory and then run the BSK setup script again.

I'm running into the same problem with VS 2022 community edition (version 17.11). I already add the --generator "Visual Studio 17 2022" argument to the conanfile.py command. Not sure if I missed some package when installing Visual Studio 2022, or there is a configuration step for cmake to find Visual Studio compiler. It looks a problem not related to basilisk, but conan-cmake-visual studio all intereact with each other. I haven't go to the laberinths of windows c++ compilers, which is definitively not my strong. If there is some expert here that went down this route and can though some light to this issue, let me knwo.

I wonder if conan 1.x supports this version off Visual Studio?

[enrique-infinite-orbits]

I'm using conan 1.65.0 and acording to https://docs.conan.io/en/1.65/howtos/vs2017_cmake.html it should support. But maybe some configuration step is mission. Anyway, I could just download VS 16 and try with that, which is the standard solution.

If you switch VS studio versions, be sure to delete the .conan folder in your home directory to reset this.
