Install and Launch

Step Action
1 Download Helios.
2 Extract the complete archive to a folder you can write to.
3 Run Helios.exe.
4 Review and accept the license agreement when prompted. Allow Windows security prompts only when you trust the downloaded package.
5 Open Tools → Preferences before using Python, inference, capture audio, or Fuser output.

Keep the packaged files together. Do not run the executable from inside the archive.

First Preferences

  • Appearance: choose language, theme, and a setup.
  • Hardware: choose the Compute GPU; optionally enable capture audio or Fuser output.
  • Python: search for or select a Python 3.10+ environment.
  • Account: sign in with Discord or a one-time email link when a feature requires access. See account setup for linking methods and copying your Input Sense ID.

Developer Mode is needed only for publishing, authoring/compilation controls, and direct input-to-output passthrough switches. It is not needed to run ordinary processed workflows or downloaded content.

Updates

Helios checks for updates after startup. Use Tools → Check for Updates for a manual check. Close other Helios windows when the updater asks, and let the update finish before launching Helios again.

Troubleshooting

  • If Helios does not start, re-extract a fresh complete package and confirm the CPU supports AVX2.
  • If Windows removed or blocked a file, restore only a package obtained from the official download and re-extract it.
  • Install optional drivers from the plugin that needs them, not pre-emptively.
  • If a Python environment is invalid, select a different Python 3.10+ environment in Preferences.
