Sudoku Help - Program License

Here's a page from the extensive help system for Sudoku Dragon. It is available as a help screen when running the program. To get the full picture Download our Sudoku Dragon and see the screen in its context.

We now offer an alternative product only available for download from Microsoft Store. This shares many features but not all of them. For documentation of the SudokuDragon for Store version see its separate help section.

A license is used to control the rights to continue to use Sudoku Dragon. It can be installed as a free trial or fully purchased.

The screen displays a summary of the license state, and information about when it was installed and by whom.

If you are in the trial period, a Purchase button will be shown allowing you to purchase a license online with the minimum of fuss. If your license is broken in some way a Fix button will be shown allowing a fix code to be entered to repair the license. Please refer to support page ➚ on the web site for more about this.

To check for and install an upgrade use the Upgrade Check option in the Help menu. If you want to move a purchased copy of Sudoku Dragon to another PC all you need to do is select the re-install purchased option when installing it and then enter your unique purchase order number.
