    Download the installer, then run Pactra-Setup-1.0.9.exe.

  2. 2

    If Windows SmartScreen appears, click More info, then Run anyway.

Its own title bar, tray icon, and keyboard shortcuts — not a browser tab.

Drag and drop

Drop contracts from Explorer or Finder straight into a new analysis.

System notifications

Hear when an analysis finishes even if Pactra is in the background.

Stays signed in

Open it like any other app. Your account and history are waiting.

Requirements

  • Windows 10 or 11, 64-bit
  • About 250 MB of disk space after install
  • Internet connection and a Pactra account
  • No admin rights required for a per-user install

Prefer the browser?

Install Pactra as a web app

Add the site to your dock or taskbar without installing the native package. Analyses still run in the cloud.

  3. 3Select "Install Pactra" or "Add to Home Screen".
  4. 4Follow the on-screen prompt to complete installation.

Instant access

Open Pactra straight from your taskbar or Dock — no browser, no typing URLs.

Focused window

Runs in its own window with no tabs, bookmarks bar, or browser chrome in the way.

Desktop notifications

Get notified when a long analysis finishes, even if you've switched apps.

Offline access

Previously loaded contracts and results stay accessible when you lose connectivity.
