My [Install Discovery for Windows.exe] is not work

My [Install Discovery for Windows.exe] is not work, I can not install, I shut off my Avg Internet Security, but still can not install, I bought my WD Duo Book over 2 months, but I can not use.

How should I do?

Which one you can’t use? …WD Duo Book or Discovery for Windows?
For what you will use Discovery for Windows? … your computer or your Duo Book don’t need it.
