After installing a newly purchased license of lumerical, I was unable to run any simulations. If I go to resource configuration: Configuration test, I receive the following error:
‘Installation test failed: invalid MPI path’
After finding no immediate advice about how to fix this, I attempted to uninstall and reinstall lumerical, only to discover that I cannot do so because of a data error associated with LFS_data.msi in the unzipping process.
However I am now concerned that in trying to uninstall and reinstall, I may have invalidated my license. Did I need to deactivate the license before uninstalling lumerical, or is that only necessary if I were to change cpus? What if I were to reinstall the OS on this machine in order to resolve my problem with unzipping the lumerical install files?
I have tried unzipping the lumerical install file both directly with windows, and with 7-zip, but both refuse to extract the .msi file because of unspecified problem. How should I go about getting lumerical installed? Thank you.
