After several attempts on different computers, with both 2011 and 2012 versions, I am continuously getting the error message: "Some installation files are corrupt. Please download a fresh copy and retry the installation." The install file downloads fine and clicking on it begins the installation process, but near the very end, the 'corrupt' message appears. Every time.
Problems downloading the Autodesk software and/or CRC errors may be avoided by using another web browser, or using the alternate browser download method.
