i have recentley tried to install norton internet security 2002 on my home P.C, i am using xp pro, and have downloaded all windows updates, including sp1. The anti virus software installs, but when trying to install the internet security, it comes up an error message and says that it cannot write to / open HKEY_LOCAL_MACHINE. VERIFY THAT YOU HAVE SUFFICIENT ACCESS TO THIS KEY. When i click OK it uninstalls. I have checked to see if i am logged on as the administrator, and this seems ok. Any solutions Please????
