Hi usersudoku,
To install Sudoku on your new system, follow these steps:
1. Download the SudokuSetup file from
www.sudoku.com/download.htm. The download is free. (What you paid your money for was the registration code.)
2. Install the Sudoku program by running the SudokuSetup file. You may need an Internet connection during installation.
3. At this stage, the program will think you are a first-time user and you will be in a 28 day free trial. Enter your registration information into the Sudoku program by selecting Enter key
from the File menu.
Regards
Scott
