Download Halo 1 off the web like installing a disk?

[revengeofthenerds]

I have Halo 1 for pc, or HAD halo, cuz i cant find the disk. I hav the product code, and i was wondering if anyone could tell me if I can find an authorized (practically out of the package) ONLINE download of the disk that needs a product code and is FREE?
