Just to clarify, Is the Ansys license manager up and running and showing the licenses that are available for checkout and you can open and run Lumerical? i.e. FDTD/MODE/INTERCONNECT directly?

Or are you still getting the licensing error indicated in your post?
I am getting Ansys License Manager Error, namely that “lumerical_gui does not exist”. License Path: 1055@localhost, FlexNet Licensing error:-5,147.
If you are still unable to open Lumerical directly with the above error please edit your "License.ini" file and change "domain=2".
See this KB article for details:> Specify license manager location non-graphically – Ansys Optics And this KB page for the location of the License.ini file on your computer:> Ansys Lumerical product preference files – Ansys Optics
