Windows cant find Virtual Com port driver

Hi,

I am trying to connect my OMAPL138 board with my PC. I got the sample code from the link http://www.ti.com/tool/starterware-dsparm and installed in my PC. I am using Windows 7.

while I run this code I can see a virtual Com port in my PC's control panel . But my PC cant find  the corresponding driver for the same.

 should I need to install separate driver for this..? 

Thank you.
