Error message when trying to install AutoCAD Mechanical

[apeowich]

Dears, here I need your help. I was trying to install AutoCAD Mechanical 2014 student version but when executing the set up file an error message is shown: FALLO DE COMUNICACIÓN (Comunication Fail). I was looking for a solution but nothing works, even following the installation tutorials. My pc is a notebook Asus N65VB with Windows 8.1 (x64). Is it possible to any of you to help me with this issue. I really need this program. Thanks
