Can't Install IDT HD Audio Driver

I use Windows 7. Under Hardware and sound it says my NVIDIA Control Panel is not found and that my IDT Audio driver is inaccessible (http://imgur.com/zin2EMY). I tried to update my IDT High-Definition (HD) Audio Driver using the HP support website but whne I tried to run the application, this happened: http://imgur.com/gO3O4mf

I even ran the program as Administrator so I have no idea what to do, can anyone help me?
