Autodesk Infrastructure Design Suite Premium 2014

Hello,
During the install of this error appeared in the middle of the process. I have the original and licensed DVD and I think it shouldn’t be a problem. Does anyone have any idea about this error ? What is causing this and how can I solve it ?
Thank you !
