The License Manager is expecting a file with a specific name for the FDI Package IDE, renaming this license file may cause the tool to not operate. Be sure not to open or modify the file named "FDI Package IDE.lfx".
License Manager will only install one license file at a time for the FDI Package IDE. If you support more than one protocol, you may need to uninstall and install the corresponding license file in order to build another protocol's device package.
