maybe you have bought the sec hand video game, that means this game is with fake serial or write the serial carefully and without mistakes
it can be valid but if its still invalid
you need to back to store and ask them why the serial is not working on the game

hope youre not trying to install it using the old serial number on the sticker on your case? It should have come with a new serial number to install. You also have to have XP or Vista to perform an upgrade otherwise you need a full installation CD.

Contact TOM TOM Support. The serial number is also on the original box

The PC serial number should be on a white bar code sticker on the back of the unit. Look for a sticker on the computer case.
