The Windows installer will attempt to install Git automatically if it is not already available.
The Windows installer will attempt to install Git automatically if it is not already available. It also tries to
install Python 3 using `winget`, `choco`, or `scoop` when Python is missing and recognizes the `py` launcher if `python`
isn't on your PATH.
**Note:** If you are using Python 3.13 or newer, install the [Microsoft Visual C++ Build Tools](https://visualstudio.microsoft.com/visual-cpp-build-tools/) and reopen PowerShell before rerunning the installer.
