COMSOL software version 5.5 installer update contains a fix for an issue that may, for certain combination of licenses, cause the installer to uninstall a LiveLink for CAD product during an update installation. The update applies to COMSOL software version 5.5 (Build: 292), version 5.5 update 1 (Build 306), and version 5.5 update 2 (Build: 352). The update can be applied directly to an installation of version 5.5.

If you have a version older than version 5.5 and a valid license that is on subscription, then perform a full installation of version 5.5 from the Product Download page, which will include all updates.

How to Apply the Software Update

Before proceeding with your installation, make sure that you close and exit any running COMSOL® processes or any software you have running that correlates to a LiveLink™ product you would like to update (Excel®, MATLAB®, PowerPoint®, or a CAD software).

To update COMSOL Multiphysics®, first download the COMSOL Software Version 5.5 Installer Update, then run the executable. After the installation is finished, the updated COMSOL Multiphysics 5.5 Installer will be automatically launched. Select an update method, then follow the steps to install the COMSOL software version 5.5 update 3.

COMSOL Software Version 5.5 Installer Update

To complete the update, make sure that both the COMSOL software version 5.5 installer update and the COMSOL software version 5.5 update 3 are installed.

In order to check that the update installation was successful, first start the COMSOL Multiphysics® software and select the About COMSOL Multiphysics menu option. If using the Windows® operating system, this is located in the File menu under Help. The listed version should be COMSOL Multiphysics® 5.5 (Build: 359).
