Hi Paul
Yes I have upgraded the e-licenser to the latest version and restarted my iMac and my key is connected to a USB socket at the rear of the iMac. Ive tried loading Vienna Strings Standalone, Vienna Ensemble, Directory Manager and still get the following message for each:
Vienna Instruments Standalone cannot be opened because of a problem.
Check with the developer to make sure Vienna Instruments Standalone works with this version of macOS. You may need to reinstall the application. Be sure to install any available updates for the application and macOS. Click Report to see more detailed information and send a report to Apple.
Regards
Kevin
