Snapper fully functions for 100 days without authorization.
If you want to maintain using Snapper after that you need to authorize by buying an activation code.
You can do that by clicking the shopping cart button in Snapper, or by going to our on-line store.

Clicking the download link or the Snapper to the right here will start the download (10 MB).
You can uninstall Snapper at any point by choosing 'Uninstall' in the Snapper menu.
