Problem when install IDT HD audio

Howdy,
I encountered this error message when I try to install the IDT software package in the computer. The installation was aborted after the error message. The problem triggered while installing Audio driver so do I need to upgrade the driver. How I can solve this error? Please help me. Thanks.
