can u instal d2 two times on one comp

[Mull3r]

as the title says and can u play both or just one at a time

[Silver Ice]

u can but u need onlyer's cd-key refiller. and u need a classic cd key and an expansion cd-key for every diablo 2 u want to install. but if u have 2 comps u only need 1 classic key and 1 expansion key, because both computers can use the same classic key

[timeforpain]

Yeah but can u use the same classic cd key at the same time on the net?
