Check the CD Key carefully. When you are entering your key, you may enter the letters in lower or uppercase, but be sure to include the hyphens between each set of five characters.

If the installer claims that your CD-Key is invalid, be sure that you are distinguishing the number "1" from the letter "l", “V” from “U”, “M” from “N”, “Z” from “7”, “B” from “8”, and “G” from “6” when typing in your CD-Key. Also note that the number 1, I’s, O’s, and zeros are not used.
Thank you _Lynx!
