Note: Installing multiple versions of Lumerical on the same computer is not recommended. However, it can occasionally be useful, such as when confirming that the old and new versions give the same results.

Installation instructions

  1. Install the older version of Lumerical first.
  2. Then install the newer version of Lumerical. When prompted, "Do Not Remove/Uninstall" the prior releases found on your machine by the installation wizard.

Tips

  • To ensure the correct product version is used, start the software from the Start menu, rather than double clicking on a project file.
  • If you run into any issues with the CAD/GUI or get license errors when shifting between versions, remove product the preference.ini files from your user folder and then re-configure your license.
