2013 Norton Internet Security Installation Question

I currently have the 2012 NIS installed on my PC.  I have 5 days until it expires, so I pucrchased NIS 2013.  I'm attemptiing to install it from the disc.  I started the installation and there is a window which reads:"Initializing Norton Internet Security  Please wait..."

 

There is also a yello progess bar with a white are flowing through it, giving the impression that the installation is in progress.

 

That was two hours ago.  I can't imagine that it is supposed to take this long, but I don't want to mess up the install.  Any advice?

 

Thanks!
