Malfunctioning of WiDi while installing last driver of Toshiba E205 S1904

Hey guys,
I am currently using a Toshiba E205 S1904, but suddenly my WiDi seems to have malfunctioned.
I immediately attempted to install the latest driver (version 2.1.38.0), but I got this error prompt, which I have posted below.

I also tried to update my WiFi and HD graphics drivers to no avail.
Please suggest what else I can do to solve this problem.
