Successfully Installed Autocad

When my computer was repaired, most of the application that I have been using were gone as the hard disk was formatted and installed with new software. I have CDs of Autocad and after installing them one by one, it asked for verification which I promptly keyed in. It was a large application, so installation took some time at least 40 minutes. I am please that it is working now and I can continue to use it to do civil drawings, design logos, etc.
