Installing and Reinstalling the Leica 3D Disto Software

Installing and Reinstalling the Leica 3D Disto Software

Overview

The Leica 3D Disto software runs on Windows and must be installed on any PC or tablet you intend to use for measurements. This guide covers a fresh installation, reinstallation after a hardware change, and what to do if the software fails to activate.

System Requirements

  • OS: Windows 10 or Windows 11 (32-bit or 64-bit)
  • RAM: 2 GB minimum (4 GB recommended)
  • Storage: 500 MB free disk space
  • Display: 1024 × 768 or higher
  • Connectivity: USB, Bluetooth, or Wi-Fi (depending on 3D Disto model)

Note: The 3D Disto software is not compatible with macOS or Linux.

Step 1 — Download the Software

The 3D Disto software installer is available from Leica's learning centre:

Leica 3D Disto Learning Centre

Download the latest version (currently v6). If you are on a v5 license, only install the v5 installer — a v5 license key will not activate v6 software. See Upgrading from v5 to v6 if you need to upgrade.

Step 2 — Run the Installer

  1. Right-click the installer file and select Run as administrator.
  2. Follow the on-screen prompts and accept the license agreement.
  3. Choose your installation directory (the default is recommended).
  4. Wait for the installation to complete, then click Finish.

Step 3 — Enter Your License Key

When you launch the software for the first time, you will be prompted to enter your license key. Your license key was provided when you purchased your Customer Care Package (CCP).

Reinstalling the Software

If you need to reinstall (e.g. after a Windows reset, tablet replacement, or software corruption):

  1. Uninstall the existing 3D Disto software via Windows Settings → Apps.
  2. Reboot your PC.
  3. Download a fresh installer from the Leica Learning Centre link above.
  4. Run the installer as administrator and re-enter your license key.

Important: Your license key is tied to your CCP, not to the device. You can reinstall on the same machine or a new machine as needed, as long as you have a valid CCP. If you receive an activation error after reinstalling, contact Advanced Dimensions support so we can verify your key with Leica.

Troubleshooting

  • Installer won't run: Make sure you right-click → Run as administrator. Windows SmartScreen may also block the installer — click More info → Run anyway.
  • Software crashes on launch: Try uninstalling fully, rebooting, then reinstalling. Ensure your Windows is up to date.
  • License key rejected after reinstall: Your CCP may have expired. See: What is the Leica 3D Disto Customer Care Package (CCP)?
