A Microsoft Store Easiest - no warnings
The Store build installs like any other app: no SmartScreen warning, automatic updates, and clean uninstall via Settings → Apps.
B Direct installer (.exe)
- Download the installer from the Downloads & Releases page.
- Run it. When Windows SmartScreen appears, click "More info" → "Run anyway".
- Follow the installer - it adds a Start Menu shortcut and uninstalls cleanly via Settings → Apps.
The warning appears only because the app is a free, unsigned solo project - the full source code is public on GitHub. You only see it once.
? Before you install
- Size. The installer is about 140 MB and uses roughly 330 MB once installed. Most of that is the bundled Python runtime and the media tools - nothing has to be installed separately.
- Antivirus. Some antivirus tools flag any unsigned installer that bundles a Python runtime, so a scanner may warn even though nothing is wrong. If yours does, the file is on GitHub Releases and can be checked with VirusTotal before you run it. The Microsoft Store build avoids this entirely.
- Updates. The Store version updates itself. With the direct installer, the app tells you when a new version is out and you download and run the new installer over the top - your settings, saved pairs and downloaded files are kept.
That's the whole setup. Unlike macOS, Windows needs no extra permissions. On first launch, connect with your Canvas URL and Access Token - the How It Works guide shows you exactly where to find both. The only optional extra: Microsoft Office (PowerPoint/Word/Excel), used solely for the Office→PDF conversions.
