Hi tux0topo, let me help you with your issue.
Are you using the Intel® WiDi Update Tool or trying to install the drivers manually?
In case you are trying a manual installtion I suggest you downloading the drivers from the computer or card manufacturer and install all drivers in the order described here: Adding Intel® WiDi to your system.
If the issue persists, please attach the installation logs with the option in the advanced editor. You may need to enable "View hidden files and folders" to find the logs.
