The free version of Columbus 4.6 allows you to experiment with the embedded sample networks provided in the UI (Data page). Also included is the ability to adjust your own networks from the Adjust File page. You can adjust networks with up to 25,000 stations and unlimited observations using this file driven tool. And, when you are ready to purchase a license, there are no additional installs to perform.

Supported Operating Systems

Columbus 4.6 is a Windows-based application that runs on Windows 10 (Pro).


Download the zipped installer file. Unzip the contents into any folder. Run the setup.exe program.

This version of Columbus requires installing the .NET 4.7.2 Framework (if not already installed). Download and install the .NET Framework 4.7.2 (runtime).

To see where the program has been installed, do the following:

  1. Launch COLUMBUS.
  2. Start Task Manager and select the Processes tab.
  3. Right click on the Columbus executable and select "Open File Location" or something similar (depending on the version of the operating system).

To unistall from Win 7, go to the Control Panel - Programs and Features dialog. Locate the COLUMBUS 4.6 application, then unistall. Use similar logic when running Win 8 or Win 10.

Touch Screen Bug

If you have a touch screen and it is enabled, Columbus 4.6 may crash. This is due to a dot Net Framework bug. Disable touch screen access and try running Columbus again.
