…erywhere (#4081)

### What

Throwing doesn't look great especially on windows debug builds:

Thew new method gives a nice error when you start from command line:
```
 build\Debug\example_dna.exe
Expected env-var RERUN_STRICT to be 0/1 true/false yes/no on/off, found ''Rerun ERROR: Failed to find Rerun Viewer executable in PATH.

    You can install binary releases of the Rerun Viewer:
    * Using `cargo`: `cargo binstall rerun-cli` (see https://github.com/cargo-bins/cargo-binstall)
    * Via direct download from our release assets: https://github.com/rerun-io/rerun/releases/latest/
    * Using `pip`: `pip3 install rerun-sdk` (warning: pip version has slower start times!)

    For more information, refer to our complete install documentation over at:
    https://rerun.io/docs/getting-started/installing-viewer
```



Also fixed typo in the C++ tutorial and added windows specific
instructions
