I bought cd keys from blizzard but i don't have the disc to install. Can i still get it to work.

Absolutely you can!
You should login to your blizzard's account, and then go to this page: https://www.blizzard.com/es-es/download/

Here you can download the Diablo II Original / Diablo II Lord Of Destruction games, and use the CD-Keys you just purchased in the process of installing.
You should start with the Original and then with LoD.

I tryd to do that after the game downloaded. It let me enter my cd key but then it says insert disc 1 for install

Can you tell us where you downloaded D2?
Did you install or try to install a previous D2 on this computer?

Yea i downloaded from blizzard. And no i made sure everything d2 related was deleted prior to install

And you made sure to manually go through the registry looking for "Diablo II" & deleting ANY suspicious keys that pop up?

if you used revo uninstaller you can ignore that^
