Windows & macOS

Two routes: the one-click installer, or — for the very latest build — finish the install on your own machine.

One-click installer

Download the installer for your platform from the downloads page:

  1. Download Scelo IDE-0.1.0-x64.exe.
  2. Run it. SmartScreen may warn ("unknown publisher") — click More info → Run anyway (the installer isn't code-signed yet).
  3. Follow the installer (you can change the install directory).
  1. Download Scelo IDE-0.1.0-arm64.dmg (Apple Silicon).
  2. Open the .dmg and drag Scelo IDE to Applications.
  3. First launch: right-click the app → Open → Open (Gatekeeper warns because the app isn't notarised yet).

Build the latest on your own machine

When you want a build newer than the last signed release, you can finish the install locally. The app code is identical on every OS; only the Electron runtime and the bundled Python/R differ, and those install natively on your machine.

1. Get the source (a small download):

git clone https://github.com/intelligentactuaries/scelo
cd scelo

2. Run the finisher — it fetches Electron + the Python/R runtime and builds a native installer:

bash scripts/finish-install.sh
The installer lands in apps/scelo-ide/build/ (…arm64.dmg).

Install Git for Windows, open Git Bash in the scelo folder, then: 

bash scripts/finish-install.sh
The installer lands in apps/scelo-ide/build/ (…x64.exe).

Just want to run it without building an installer?

bash scripts/finish-install.sh --run

Note

The first run downloads ~1 GB (Electron + the bundled runtime) and can take 10–30 minutes (R compiles a large package set). After that, Scelo runs fully offline.
