OTTO runs on your PC.
And it starts working right away.
The spotter, the overlays and the pit wall run on your machine and need no account. Sign in only when you want to talk to OTTO — the radio, the coach and the setup co-driver.
SHA-256: 1e6e9b7a51b608f069d9bbd7fa24adc72994e89ad970e3db778949b8b36a91ce
Windows is going to warn you. It's expected.
OTTO doesn't have a code signing certificate yet, so Windows shows a blue "Windows protected your PC" screen for any program it hasn't seen before. It isn't a virus warning — it means the publisher isn't registered yet. This is how you get past it:
- Click More info on the blue screen.
- Click Run anyway.
- That's it. Windows won't ask again on this machine.
If you'd rather check for yourself first: the SHA-256 above is the fingerprint of the exact file we published. In PowerShell, run Get-FileHash on the downloaded file and compare — if the two match, nothing altered it on the way to you.
