Once installed make sure all those utilities are accessible in your `PATH` .

If you want to be able to build x86 targets from an x64 host install the right toolchain:
```cmd
rustup toolchain install stable-i686-pc-windows-msvc
rustup target add i686-pc-windows-msvc
```

In order to load all the C++ utilities installed by Visual Studio you can run the following in a terminal window.
```
2022-05-26 21:58:27 +02:00
call "C:\Program Files (x86)\Microsoft Visual Studio\2019\BuildTools\VC\Auxiliary\Build\vcvarsall.bat" amd64
2021-04-29 16:36:10 +02:00
```
You can replace `amd64` with `x86` depending on your CPU architecture.
