Reboot the computer. Install 2010 edition.
I have had numerous problems since upgrade. I have a 3 user version 2009 and have upgraded 1 desktop unit and 1 laptop. The laptop has given so much grief that i removed 2010 and reinstalled 2009. Just yesterday the desktop unit Norton quit working and the windows XP (i love it) popped up a security screen that showed windows firewall was on and my antivirus program was not enabled. I tried with no success to re-enable the Norton. I will uninstall the 2010 and reinstall 2009 on this unit also. Can this be a virus problem? Are there known problems with Norton 2010? I had recently posted problem with the Norton icon on the taskbar had a red checkmark on it. Now there is a red x on the icon.
