During the time you are running a trial of form.suite4.net the program will remind you of the number of days remaining for the trial period on startup.
Clicking on "Buy Now" (1) will take you to a purchasing page at http://www.suite4.net where you can acquire a license for continued use of the product beyond the end of the trial period. After payment has been received an email containing a license file will be sent to you.
After you have purchased a license through our web site you will receive a text file with the license data. When the reminder window shown above appears the next time you start form.suite4.net, click on "I already have a license" (2). This will bring up the "Select Existing License" dialog.
Browse to the license file you received and click "OK". This activates the software permanently.
Note: Be sure to store the license key in a safe location so it is available when you reinstall the program at some other time.
