I download Diablo 2 from stray on here and I'm so confused. It immediately went to 7zip so I unzipped it and there was only three ISOs. One was cinematics, the other was install and the last one was play.

If you have images of all 4 CD then i don't understand the problem. In fact for installation even subchannel information does not matter - only to play.

As far as i rememeber when you install LOD then original Diablo2 play CD is not needed anymore - if it asks Playdisc then you need to insert LOD disc, not original Diablo2 play disc! You can safely remove your original 3 CDs for a long time - you won't need them anymore at all. Of course make sure you made FULL install of original Diablo2 before installing LOD. I discovered the problem. Problem was: There were problems with the image, which I traced back to a problem on the actual original cd.

Download windows 7 gamer edition x64 single link. Which refused to allow the installation to copy a file when using daemon tools. After I burnt the image it was fine.
