Most probably your hardware ie graphic card do not support software requirements.

or
Intel or AMD Dual Core processor, 1.6 GHz or greater
•1 GB RAM
•750 MB free hard disk space for installation
•1024x768 VGA with true color
•Microsoft Internet Explorer 6.0 (SP1 or higher)
If you are using AutoCAD for 3D modeling, you should bump up your system as follows:
•Intel Pentium 4 processor or AMD Athlon, 3.0 GHz or greater
or
Intel or AMD Dual Core processor, 2.0 GHz or greater
•2 GB RAM or greater
•2 GB of additional free hard disk space
