Upgrading Sudoku Dragon

Sudoku Dragon is designed to be easy to upgrade, you do not need to re-install the product in order to upgrade it. You can update the product by using the Sudoku Dragon Update Check command from the Help menu to check for and download updates. During the initial trial and the first year all updates are free.

Using the Update Check... option from the Help menu in Sudoku Dragon compares the installed version against those available on our web site and indicates which (if any) is the most up-to-date compatible version to download. Download and installation occurs within the Sudoku Dragon program itself.

On rare occasions it will be necessary to re-install and re-configure the software if a very old version is in use. Note that an update does not affect your Sudoku Dragon license in any way, a trial licence is not extended or renewed. The puzzle file format may need to be enhanced over time, generally all puzzles can be handled in the most up-to-date version, if you have an old version of the program you may not be able to load newly generated puzzle files.
