Installation
Base Requirements
- 64-bit Windows 10 or Windows 11
- An AVX2-capable processor
- A supported controller, keyboard/mouse, capture source, or output device for the workflow you plan to use
- Internet access for downloads, updates, sign-in, and Online Resources
Optional Requirements
| Feature | Additional requirement |
|---|---|
| Live video and computer vision | A supported capture device or OBS source; use Dataset Playback for saved-media tests |
| CV Python and Python-assisted tools | Python 3.10 or newer selected in Preferences |
| Detection, pose, segmentation, OCR, or engine building | A compatible GPU selected in Preferences; TensorRT engine building requires a compatible NVIDIA selection |
| Virtual controller output | ViGEmBus; the ViGEm Output panel can launch its installer |
| Console hardware output | Titan Two or Makcu hardware and its normal console/controller connections |
| Remote Play | A console/account that can use Remote Play and a reliable local network |
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 â 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, or create one with Manage Python Environments. See Python Environments.
- 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 exposes publishing, selected authoring controls, and direct input-to-output passthrough switches. GPC 3 source compilation is available through its memory slots without Developer Mode. It is not needed to run ordinary processed workflows or downloaded content.
Updates
Helios checks for updates after startup. Use Tools â 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.
