Hi @abhishek-appana, installing the IDAKLU solver on Windows is tricky and we haven't added instructions to do so, yet – but we plan to do so with #4242 and other follow-ups. A short guide is as follows:

1. Set up a C++ compiler: we use a recent version of MSVC, which you can get using Build Tools for Visual Studio Code 2022. Note that you won't need Visual Studio 2022 entirely, just "Desktop development with C++" should be enough.
2. Next, you'll need the vcpkg package manager for C++. You may get it here: https://vcpkg.io/en/. vcpkg should set up all of the prerequisite dependencies for you.
3. You can then do pip install -ve . inside a git clone of the PyBaMM repository. Before that, you'll need to set a bunch of environment variables as follows:

   PyBaMM/.github/workflows/publish_pypi.yml

   Lines 78 to 83 in 48b4e48

   	PYBAMM_USE_VCPKG=ON
   	VCPKG_ROOT_DIR=C:\vcpkg
   	VCPKG_DEFAULT_TRIPLET=x64-windows-static-md
   	VCPKG_FEATURE_FLAGS=manifests,registries
   	CMAKE_GENERATOR="Visual Studio 17 2022"
   	CMAKE_GENERATOR_PLATFORM=x64

In any case, the easier method, if you have elevated privileges on your machine, is to use WSL2: https://docs.pybamm.org/en/stable/source/user_guide/installation/windows-wsl.html and follow the instructions for GNU/Linux after that.
