i downloaded an iso of halo and installed it,had a key to go with and everything went off without a hitch,until i tried to play it.it said i was missing a dll,so i downloaded it and installed that into the proper directory,and it tells me its missing another.last time i went down this rabbit hole,i ended up downloading several dlls only to find out that it just refused to play.
on top of that,i read i needed to run the dll with regsvr32,but i got a message that it might not be compatible with my system (windows 7 64 bit).
what do i do?
