Based on the information you provided and the specifications available online, I was able to determine that you have a first generation Intel® Core processor with Intel® HD Graphics, which supports Intel® WiDi software 3.0 for Windows* 7.
Miracast* is only supported in Windows* 8.1 with third generation Intel® Core processors or newer.
Thanks joe_intel. I ran the Intel WiDi Update toll and got the following message:
"Installation failed your system has an Intel WiFi adapter that is not supported by the update tool"
"The WiDi update tool does not support the Graphics adapter installed in your system Your platform is not WiDi compatible.
I guess I am out of luck for Miracast. I will just run a long HDMI cable. Thanks for the information
