After installing Norton Utilities 15 and clicking on the nu.exe ( the NU short cut icon created on the desktop during the installation) to start the program I get a strange response. First there’s the small black “Norton Utilities” screen and then instantly “Windows Installer” screen opens and starts running. The only option is to press “cancel” and if you do Windows Installer runs “Cancel” for a few minutes but does nothing then starts running the install program again. Only after about 2 minutes the Norton Utilities program finally runs. Allowing the Windows Installer to run its coarse makes no difference because each time you open Norton Utilities the Windows Installer will run. I’m running Windows XP Pro 3 & also running Norton Internet Security 2012. I purchased the NIS 2012 & Norton Utilities 15 (NU) together as a package in December 2011 through the Norton website… download only no disc. I’ve been running NIS or Norton Anti-Virus continuously for over 10 years. In 2011 I purchased Norton System Works & deleted it prior to installing NU & NIS 2012. I downloaded & ran the Norton Removal Tool twice after 2 useless attempts of uninstall & re-installing NU. Thanks for any help and/or suggestions…
