The installer is code-signed — Windows SmartScreen now shows the verified publisher (David Kohout). It may still warn on first launch until the new signature builds reputation; click More info → Run anyway.

Who is this for?

SimLauncher is built for people who run non-trivial sim setups and are tired of manual prep every time they want to drive.

You'll likely benefit from this if you:

• Run multiple sims (iRacing, AC, ACC, AMS2, etc.)
• Switch between different setups (VR vs triples, motion on/off, etc.)
• Use multiple companion apps (SimHub, CrewChief, overlays, telemetry, wheelbase software...)
• Care about launch order, delays, and reliability
• Want a single click to go from desktop to fully ready rig

This app is probably unnecessary for you if:

• You run one sim and one or two apps
• You're fine with everything starting with Windows
• You don't need different setups (e.g. always same screens, same config)
• You don't care about launch order or coordination between apps

In that case, your current setup is already simple enough.

Troubleshooting

"Windows protected your PC" (SmartScreen)

The installer is code-signed (verified publisher: David Kohout), but Windows SmartScreen reputation builds up over downloads and time — so it may still warn on first launch until then. Click More info → Run anyway. You can confirm the signature yourself in the installer's Properties → Digital Signatures tab.

A game won't launch

• Check that the executable path in Settings points to the correct .exe.
• If the game is already running, SimLauncher intentionally skips re-launching it (reported as "skipped — already running"), so this is expected rather than a failure. Close it first if you want a fresh launch.
• If the game needs elevated permissions, try running SimLauncher as Administrator.

A utility isn't detected as running

• Some utilities (e.g. SimHub) take longer to start — increase the launch delay in Settings.
• Process detection matches by the executable's file name (not the full path), so a renamed copy you've configured is detected. Detection can fail when the app launches a differently-named child or wrapper process — add that process name under "Secondary executables to watch" in the profile editor — or when two different files share the same .exe name.

Auto-updater isn't working

• Make sure your firewall/proxy allows github.com and objects.githubusercontent.com.
• If an update hangs, restart SimLauncher — it retries on the next launch.

Building from source

You can build the installer yourself instead of trusting the published binary. It's a standard Electron + electron-vite project; you need Node.js 24 or newer.

git clone https://github.com/Stashpeak/SimLauncher
cd SimLauncher
npm install
npx install-electron   # Electron >=42 no longer downloads its binary via postinstall
npm run dist:win:unsigned   # build an unsigned Windows installer into dist/

npm run dist:win builds the signed installer, but that requires the Azure Artifact Signing credentials, which only exist in CI — use dist:win:unsigned locally instead. See CONTRIBUTING.md for details.

For the full development workflow — running in dev mode, the test/lint/typecheck gates, and how to add a game or utility — see CONTRIBUTING.md.

Trust & transparency

• The source is public and licensed under GPL-3.0 — you can read every line, the full commit history, issues, pull requests, and CI runs before trusting a binary.
• You can build it yourself from source (see above) instead of running the published installer.
• Releases are built in CI from tagged commits, and each release's notes link the issues and PRs behind every change.
• Every release is verifiable: each one ships SHA256SUMS.txt to confirm the installer's integrity and a CycloneDX sbom.cdx.json listing the full dependency inventory.
• Development is AI-assisted (Claude Code, Codex & Gemini) with human review on every change, disclosed openly in the commit history.
• Security issues should be reported privately — see Security.
