Neithan, kindly share more information about your system so we can find out what is happening. You can try generating a code from the Intel® System Identification Utility or providing a copy of the msinfo32 report (Windows* key + R, type “msinfo32”, click OK, and then File, Export). If you need to attach the file, it can be done by using the Advanced Editor link on the upper right corner when replying.
Are you trying to install any specific Intel® WiDi software version or using the Intel® WiDi Update Tool?
