For you to have the best experience in the HP forum I would like to direct your attention to the HP Forums Guide I grasp you are having an issue with the installation of the Dolby home theater V4.

Here is a link from the WindowsSevenForum that may help. If that does not work I would try a When I checked the specifications for your notebook I noticed that it came with Free Dos. Have you done all your Windows updates?

If none of the above has helped, I suggest you do a fresh installation of your Windows. Best of Luck!
