Installation

UsingOpen Studio runs on macOS (Apple Silicon), Windows (x64), and Linux (x86_64). You download it with a license key; every file is verified against the SHA-256 shown on the download page.

Before you start

A license key from your purchase email. Keys are issued after the $19 Wise payment is verified, normally within 24 hours.
Each key allows ten downloads within 72 hours. Each download click, or one run of the one-line installer, uses one.
The installers are not signed or notarized yet, so macOS and Windows show a first-launch warning. The first-launch guide walks through both.

Direct downloads

Open the download section, enter your key, and pick your platform:

UsingOpen-Desktop-MacOS.dmg          75 MB   macOS, Apple Silicon
UsingOpen-Desktop-Windows.exe        71 MB   Windows, x64
UsingOpen-Desktop-Linux.AppImage    229 MB   Linux, x86_64
UsingOpen-Desktop-Ubuntu.deb         75 MB   Ubuntu / Debian, amd64

One-line installers

macOS and Linux:

curl -fsSL https://usingopen.com/install.sh | bash

Windows (PowerShell):

iwr -useb https://usingopen.com/install.ps1 | iex

The installer asks for your license key, downloads the matching build through the licensed download endpoint, verifies its SHA-256, and starts the app.

Verify a download

The download page shows the SHA-256 for the file you just fetched. Check it before installing:

# macOS
shasum -a 256 ~/Downloads/UsingOpen-Desktop-MacOS.dmg

# Linux
sha256sum ~/Downloads/UsingOpen-Desktop-Linux.AppImage

# Windows PowerShell
Get-FileHash $HOME\Downloads\UsingOpen-Desktop-Windows.exe -Algorithm SHA256

If the hash differs, delete the file and download it again. If it still differs, email [email protected].

License keys and limits

A key is valid for 72 hours after it is issued.
A key allows ten downloads in that window.
Keys are not tied to a device; there is no activation step in the app.
Expired, exhausted, revoked, or unknown keys are rejected by the download endpoint with a message that says which case applies.
