How to install Prism & Parallax in PixInsight (and fix "no updates available")

I recently set up SyQon DeepPrism AI and Parallax (Deblur & Star Corrector) in PixInsight and hit a few snags, so here's the full process. **How it works:** each SyQon product has two parts — a CLI engine (the zip you download from your syqon.eu dashboard) and a PixInsight script that drives it. The dashboard zip alone won't show up in PixInsight; you need both. **Step 1 — CLI engines.** Download your purchased builds from the SyQon Download Center, extract each zip to a permanent location (e.g. a folder on your data drive). Keep each `*_cli.exe` together with its `_internal` folder — they don't work apart. **Step 2 — PixInsight scripts.** Add this repository in Resources → Updates → Manage Repositories → Add: `https://raw.githubusercontent.com/SyQon-Hub/PixInsight_Scripts/refs/heads/main/` Then Resources → Updates → Check for Updates → Apply, and restart PixInsight. **Step 3 — the gotcha.** On PixInsight 1.9.4 (build 1975) the updater says "There are no updates currently available" — the SyQon repo currently declares compatibility only up to 1.9.3, so PI silently rejects it. Manual workaround: 1. Download the latest `SyQonScripts*.zip` from https://github.com/SyQon-Hub/PixInsight_Scripts 2. Extract it anywhere permanent 3. In PixInsight: Script → Feature Scripts → Add → select the extracted `src/scripts` folder → OK → Done 4. Prism, Parallax, and Starless now appear under Script → SyQon **Step 4 — connect the engines.** Open each script, and in the Executable section at the bottom point it to the matching CLI exe from step 1 (Prism → `prism_cli.exe`, Parallax → `parallax_cli.exe`). The path is remembered. Licensing is account-based — it verifies against your SyQon login on first run, no key to paste. Notes: first Prism run can be slow while the ~400 MB ONNX model loads. If you later move the CLI folders, re-point the scripts. Since the manual install bypasses the update system, grab new script versions from the GitHub repo when SyQon releases them. Clear skies!

I got the same error after step 4, and adding _194 doesn't change it. I am a bit frustrated about this ...

Same. It says: "*** Error: The legacy 'sm' JavaScript engine is not available in this PixInsight build" when I try to launch the script. Something is broken

Ok it's working now but I must say it is very complicated !

Just as an FYI. I got a new link from support that supports the latest version 1.9.4 of PixInsight and all is working well. Regards

I finally got it installed but it was a royal PIA. If it were not for this post I would have never been able to install it.

Followed instructions to the letter. Parallax Isn't showing up under SyQon. Only Prism and Starless. I also only see one cli, the parallax_cli.exe. I believe it's an all in one? I raised a ticket. Hope it gets resolved soon. Pixi 1.9.4. So far quite an underwhelming experience consider the 127 euro price tag. If anyone else has experienced this and has a work around I would be most grateful. Cheers
