Software Activation
The Accudyno software no longer requires an activation key. Just download the latest version, install it and connect your unit: it will work automatically.
You can download the software from accudyno.com/software.
Is the software asking for a key?
If a screen appears asking for an activation key when you open the software, it means you have an old version. Download and install the latest version from the website and it will no longer ask for a key. You can open that screen from the Help menuActivate Software.

Installing on several computers
You can install the software on any PC, as many times as you want, with no limit. If you format the computer or change machines, just install it again.
