When you launch Vuo, if you haven't activated your license yet, Vuo will show a dialog. Click the Activate Vuo button. This opens a vuo.org page in your web browser, telling our server that you want to activate Vuo.

With some web browsers, Vuo is able to activate automatically when the web page opens. Vuo shows a dialog saying that it's activated.

Other web browsers require one extra step. Vuo shows a dialog asking you to enter an activation code. You can find the activation code on the vuo.org page that was automatically opened. Copy the activation code from that web page and paste it into the dialog.
