Hello there, I know this post is a bit old but I´m having the same problem with the installation. Already tried to install several versions and either appears the corrupted file error or for the newer versions like 2013 2014, it doesn´t even start the installation manager. I have already turned off the firewall and antivirus but still can´t manage to install a simple 2010 version of the Autocad. And yes, all my operational system attends the prerequisites. Its an w7 premium, 64 bits, 4gb. I´d appreciate a response. Thanks
Tom
Hello Thomaz!
Can you please confirm what download delivery methods you've tried (Install Now, Download Now, Browser Download)? Have you tried turning off your firewall and antivirus software temporarily?
