Installation Instructions

To download and install (or upgrade to) the current version of Uppaal:

1. Uppaal graphical user interface requires Java version ≥17 installed. We recommend Open JDK:

   • Windows: download and install Open JDK from Adoptium.
     During installation select JavaSoft (Oracle) registry keys:
     
     Otherwise uppaal.exe may not find Java and fail with This application requires a Java Runtime Environment 11.0-21.0, even though Java is already installed.

   • macOS: download and install Open JDK from Adoptium.

   • Linux: make sure that full JRE (Java Runtime Environmnent) is installed (headless variants do not support graphics, therefore are not enough), e.g.:

     • Ubuntu/Debian: sudo apt install openjdk-17-jre
     • Arch: sudo pacman -S jre-openjdk
     • Fedora: sudo dnf install java-17-openjdk.x86_64
     • NixOS: nix-env -iA nixos.jdk17

   • Command line utility verifyta does not use Java, hence Java is optional if you use only verifyta.

2. Choose and download Uppaal version from the download area.

3. Extract Uppaal distribution archive where it will be accessible: C:\Program Files, /Applications, /usr/local, /opt/local or simply user Desktop are fine locations as long as you have permissions.

4. Optionally, integrate within your desktop environment:

   • Windows: run AddLinks.vbs script to create shortcuts in the Start menu and/or Desktop.
   • macOS: drag and drop Uppaal app folder into /Applications (since Uppaal 5, Uppaal Stratego 10).
   • Linux: run AddLinks.sh script to create a shortcut in Start menu.

5. Launch Uppaal by either clicking on uppaal.jar, uppaal.exe, Uppaal.app or uppaal launcher.

   • macOS may put Uppaal into quarantine and suggest to “Move to Bin”:
     
     To work around the quarantine, right-click (two-finger tap) and choose Open and then Open again:
     

6. Launch and enter your license key and the period for license-computer offline binding period:

   • Command line: verifyta --lease 168 --key YOUR_LICENSE_KEY, or
   • Graphical user interface when Uppaal is started:
