Restart Required to complete installation previously installed patch

Installed Windows 7 Professional with Service Pack 1 (32 bit).  Reinstalled N360 Premier(version 21.6.0.32) from website.  Following installation and Live Update, restarted PC.  After reboot, the message appears on the home screen that a previously installed patch requires a restart to complete installation.  The computer has been restarted 25 or more times and the message still pops up every time. What part am I missing??? I went through the first 12 pages of this forum and didn't see anything similar so I apologize if this is an old questions.  Thanks for any help,  Don O
