VSL Vienna Key
The ViennaKey is a USB protection device by eLicenser (formerly Syncrosoft) and is required to run any Vienna Instruments or Vienna Symphonic Library software. It is not included in the products of the Vienna Symphonic Library and has to be purchased separately.
If you already have another eLicenser USB protection device (e.g., from Steinberg or Arturia), you can use it for our products, too. Otherwise we recommend ordering a ViennaKey together with your first purchase.
