Hotspot Shield 1.07 installationerror occurred

Hi all,
When I am in the middle of Hotspot Shield 1.07 installation I stuck up with this below error message. Because of this error I am not able to continue with the installation process. Do I need to install the TAP VPN device driver separately? I tried to re-install the Hotspot but again in the point I am getting this error. Please help. Thank you.

An error occurred installing the Tap VPN device driver.
