I appear to have successfully downloaded the file twice. I then get a message that the file is corrupt when I try to install.
I am using Windows 7/64 bit with plenty of memory.
I worked around the problem. DL'ed the file to a removable drive and installed from there. The original problem occurred while extracting the file on the computer. I have no idea why this would be different other than the removable drive is not the OS drive.
