Currently only 64-bit versions of Windows are supported. 32-bit Windows can use the :doc:`Legacy GNU Make Build System<../get-started-legacy/windows-setup>`.
ESP-IDF requires some prerequisite tools to be installed so you can build firmware for supported chips. The prerequisite tools include Python, Git, cross-compilers, CMake and Ninja build tools.
For this Getting Started we're going to use the Command Prompt, but after ESP-IDF is installed you can use :doc:`Eclipse <eclipse-setup>` or another graphical IDE with CMake support instead.
Previous versions of ESP-IDF used the :doc:`Legacy GNU Make Build System<../get-started-legacy/windows-setup>` and MSYS2_ Unix compatibility environment. This is no longer required, ESP-IDF can be used from the Windows Command Prompt.
The installer includes the cross-compilers, OpenOCD, cmake_ and Ninja_ build tool. The installer can also download and run installers for Python_ 3.7 and `Git For Windows`_ if they are not already installed on the computer.
ESP-IDF Tools Installer creates a shortcut in the Start menu to launch the ESP-IDF Command Prompt. This shortcut launches the Command Prompt (cmd.exe) and runs ``export.bat`` script to set up the environment variables (``PATH``, ``IDF_PATH`` and others). Inside this command prompt, all the installed tools are available.
Note that this shortcut is specific to the ESP-IDF directory selected in the ESP-IDF Tools Installer. If you have multiple ESP-IDF directories on the computer (for example, to work with different versions of ESP-IDF), you have two options to use them:
1. Create a copy of the shortcut created by the ESP-IDF Tools Installer, and change the working directory of the new shortcut to the ESP-IDF directory you wish to use.
2. Alternatively, run ``cmd.exe``, then change to the ESP-IDF directory you wish to use, and run ``export.bat``. Note that unlike the previous option, this way requires Python and Git to be present in ``PATH``. If you get errors related to Python or Git not being found, use the first option.
If the ESP-IDF Tools Installer has finished successfully, then the development environment setup is complete. Proceed directly to :ref:`get-started-start-project`.
