Get Fat Controller running.
A signed installer sets up the daemon and CLI, adds Start Menu shortcuts, and launches Fat Controller. Signed by Calapi LLC — verified automatically before anything is installed.
Prefer a script? Install from PowerShell instead
irm https://dl.fatcontroller.app/latest/install.ps1 | iex
Run from an ordinary PowerShell prompt — no admin rights needed. Installs to
%LocalAppData%\Programs\FatController, verifies the download's SHA-256
digest and Authenticode signature, and starts Fat Controller in the system tray.
Re-running this command later reinstalls the current release in place.
1. Check the SHA-256 digest
Get-FileHash '.\Install FatController.exe' -Algorithm SHA256
Compare the Hash value it prints against the published digest at
Install FatController.exe.sha256 —
the two must match exactly, character for character.
2. Check the Authenticode signature
Get-AuthenticodeSignature '.\Install FatController.exe' |
Format-List Status, SignerCertificate
Status must read Valid, and the signer certificate's
Subject must read CN=Calapi LLC, O=Calapi LLC, L=Bethesda, S=Maryland, C=US.
No PowerShell? Right-click the downloaded file → Properties → Digital Signatures tab shows the same
signer information.

Installing the daemon is the easy part — an account is what turns it into shared, visible, coordinated operational infrastructure.
