Installing OrOrbit

If your OS shows a warning, that's expected for early builds. Here's why — and how to get past it.

Why aren't OrOrbit applications signed?

Thanks for being one of the early users!

Code signing isn't free — Microsoft requires paid certificates from authorized vendors. Until OrOrbit grows enough to fund one, our installer will trip a SmartScreen warning the first time you run it.

The good news: signing only proves who published the installer, not what's inside. OrOrbit's source is public, so anyone can audit exactly what runs on their machine — read every line on the public mirror.

Windows

Two clicks past the warning and you're in.

Run the downloaded .exe. When the blue "Windows protected your PC" popup appears, click More info, then Run anyway. Approve the standard UAC prompt and the installer takes over from there.

Auto-updates inside the app work the same way — you'll see the UAC prompt each time, but no SmartScreen popup after the first install on the same machine.

Smart App Control

Windows 11's Smart App Control (SAC) blocks unsigned installers outright with no bypass — and SAC is the future of Windows app trust, so this matters. It's opt-in on fresh Windows 11 installs and most users today don't have it on, but adoption is climbing.

If SAC is enabled on your PC, you have two options: disable it (a one-way toggle — you can't turn it back on without reinstalling Windows) or wait for OrOrbit to ship signed builds. The fix is on our roadmap; until then, the SmartScreen click-through path above only works for users without SAC.

Verify your download

Optional but recommended. Each release publishes a SHA256SUMS.txt file alongside the installers; compare your downloaded file's hash against the entry in there. 

certutil -hashfile OrOrbit-Setup.exe SHA256

The matching hash is listed in SHA256SUMS.txt under the GitHub release asset name (e.g. OrOrbit_0.1.0_x64-setup.exe). The bytes are identical — only the saved filename differs.

Read the source

Every line of code that ships in the installer is public. Audit it, fork it, contribute back.
