Norton Antivirus 2009 Not Installing

I recently purchased Norton Antivirus 2009 and tried installing it on my new computer.  The computer is an HP Pavilion running Windows Vista Home Premium 64-bit.

 

I inserted the CD and ran through the install.  It told me to restart the computer so that the installation could continue.  I restarted the computer as it instructed. When the computer booted up, the Norton install screen popped up and gave me the exact same message as I previously had, in that, the computer needed to restart to continue the installation.

 

I tried rebooting a few times and it seems like the install is getting stuck at that juncture.  Any ideas on what's going on and what I can do to remedy this?

 

Thank you!
