The Sacred Amulet

I have found and want to purchase this old game at Amazon. I had the game many years ago, but do not remember if you had to have a cd key to install. If anyone remembers and can help me, it would be appreciated.

Game is from 1999 or 2000, apparently there was a 2001 reissue.
No CD key, though it probably had a disc check.

Jenny100, Thank you for you time and help. I will make the purchase. This was one of the many games I lost in my move.
