You can use one ViennaKey for all of your Vienna Symphonic Library products, as long as you run them on one single machine. Of course you can distribute Vienna Instruments Collections as you wish over several computers, e.g., Solo Strings and Chamber Strings on computer A and Orchestral Strings and Brass on computer B. This will require two ViennaKeys. Working with VSL products on more than one computer simultaneously requires one ViennaKey (with the respective licenses) for each computer.*

Use the eLCC software (eLicenser Control Center) to download your licenses onto your USB protection device after you’ve received them with your Serial Number Certificate or via email. Later on, you can also move the licensing information from one ViennaKey to another, but you can’t store the same product license on two ViennaKeys at the same time.

Before you start, please make sure you have installed the latest eLCC software, which you can download from the eLicenser website, free of charge. Don’t forget to register ALL of your eLicenser USB Protection Devices at MyVSL. This applies to ViennaKeys as well as to eLicenser USB devices not issued by the Vienna Symphonic Library!
