Hello Alexey,

I have removed all your computers from the license database. You can now activate up to two PC running Windows 10.

To install Audirvana on your PC, you can proceed as follows:

  1. install trial version : https://audirvana.com/try-windows/
  2. unlock it by loading your license key
