Install the latest SDK version on the PC that you want to use and run the "Regula Licensing" ("Regula Keys") application (Start -> Regula Licensing).
In the application window, click the button "Send system info" to send us a request containing your contact details, comment on why you need the license and the system information the license will be bound to.
We will create a license and send it back to you in this ticket.
Once you get the license, run the application again and click "Install license", then select the license file.
After this, SDK will work on this particular PC using the software license.
