Best practices for deployment in an organization

  • Test upgrade first on a nonproduction workstation with representative projects.
  • Maintain a documented change log and rollback plan for each machine updated.
  • Schedule updates outside of critical surveying campaigns.
  • Communicate with field teams and instrument techs about firmware and software compatibility.
  • Keep at least one machine with the older version until all teams confirm the new version is stable.
  • Keep backups of all raw instrument data and final deliverables in an external repository.

Error 2: Crash on launch (“KERNELBASE.dll”)

Cause: Corrupt Leica Survey Office registry keys from an older version. Fix: Test upgrade first on a nonproduction workstation with

  • Delete this folder: C:\Users\[YourName]\AppData\Roaming\Leica Geosystems\LSO\Cache
  • Run LSO as Administrator (right-click → Properties → Compatibility → Run this program as administrator).

License, activation, and dongles

  • LSO uses license mechanisms that vary by organization: Dongle (USB), software license key, or server-based license manager.
  • Before updating, ensure your license remains valid for the target version. Some upgrades require an updated license file or a new dongle firmware update.
  • If using a USB dongle, do not uninstall the dongle driver; update any dongle drivers only if Leica’s instructions require it.
  • If license activation is handled by IT or Leica support, coordinate with them before updating production systems.

Rollback strategy

  • Keep original installer for the previous LSO version.
  • If the UPD installer supports uninstallation, use Windows → Apps → Uninstall to revert; otherwise, reinstall the older version after uninstalling 2.21.
  • Restore project folders, templates, and configuration files from backup.
  • Reinsert or reconfigure licenses as required.

3. Step-by-Step Installation Guide

If you have the original installation media (CD) or a safe backup of the installer:

Step A: Run as Administrator

  1. Locate the Setup.exe file.
  2. Right-click the file and select Properties.
    • Go to the Compatibility tab.
    • Check "Run this program in compatibility mode for:" and select Windows XP (Service Pack 3) or Windows 98/Me.
    • Check "Run this program as an administrator."
  3. Run the installer. If the installer fails instantly, the setup file might be 16-bit, which 64-bit Windows cannot run at all.

Step B: Handling the Hardware Key (Dongle) Old versions of Leica Survey Office often required a hardware dongle (Rainbow Sentinel or WibuKey) plugged into the parallel or USB port to run.

  • If you have the dongle, ensure you install the specific dongle drivers (often found in a Driver or Sentinel folder on the CD) before plugging it in.
  • Without the dongle, the licensed version will not start.

Step C: Data Transfer (USB to Serial) Since modern computers lack 9-pin Serial ports:

  1. Purchase a USB-to-Serial Adapter (Genuine FTDI chipsets are recommended; cheap Prolific clones often fail with legacy instruments).
  2. Install the adapter drivers.
  3. Plug the adapter in and check Device Manager (Right-click Start Button > Device Manager) to see which COM Port number was assigned (e.g., COM3, COM4).
  4. Open Leica Survey Office, go to Settings > Interface, and select that specific COM port.
  5. Baud Rate: Set this to match your instrument (usually 9600 or 19200).
