Cannot run Windows Update with Windows 7 SP1 with Norton Internet Security

I have run Norton Scan and Detailed scan.  I have run Malware and Hitman Pro and have no issues.  But I cannot run a successful Windows Update.  I always get error 8024402C.  I am wondering if by not uninstalling my Norton 60 day trial before installing Norton Internet Security 2010 I have caused some problem.  

I believe I have done everything to ensure Windows 7 is okay.    Can Anyone Please HELP.
