When you install and run Stonefield Query, it runs as a 30-day "unactivated" version. This version has all of the features of the full-working program, except it only functions for 30 days after running it for the first time and certain output types only output 20 or less records.

If you need more time to evaluate Stonefield Query, you can request that the demo period be extended. You have to provide contact information (name, company, address, and so forth) and an email address to which an extension code can be emailed. Enter the extension code provided in the appropriate place in the "Welcome" dialog that appears every time you start Stonefield Query, and you can use the program for 30 days more.

When you purchase Stonefield Query, click the "activate" link in the Welcome dialog to activate the program. There's nothing new to install and all of the reports you created are still available.
