Trying to install Diablo II on my computer and while installing the d2char.mpq file the install quits it give a data error (cyclic redundancy check) How do I fix this?
I hope you realize this thread is almost 10 years old.I had the same problem and have solved it! Well I got help from Blizzard, but it worked! I knew it had a link with windows. I have CD games in good working order and that I have had since diablo II came out. What the issue is that something on your computer is blocking the d2char.mpq to be downloaded. You need to find that "thing." Now, I downloaded both games and installed them from the digital downloads. I have not tried the CDs. I did have the same problem occurring prior to the changes that I made to fix the problem with the digital downloads.
1.) Turn off windows firewall. (you can find out later how to make diablo II and LOD an exception for blocking)
2.) Make sure to have up to date versions of any other virus checkers you may have
3.) Find a norton virus tool remover. Any of those virus checkers like that see if there is an official remover for it. I have not had norton on my computer in a long time, but after I did that I saw an immediate difference.
4.) Make sure your account is administrator. If not, create another login and make that an administrator.
5.) Try downloading it from the battle. net site with a digital download to make sure that there is nothing wrong with your CDs
Overall: Need to find out what is blocking the installation. Hope this helps!
