Purchased Norton Internet Security 2005, had difficulty getting product to install. Followed numerous instructions on the symantec website, with the result being that it is now installed but will not run. When we attempt to start Norton, we get the following message "nmain.exe unable to locate component, symneti.dll was not found". Clearing that error message gives us another error message "unable to start symantec integrator' The pop-ups suggest uninstalling and reinstalling, but we are reluctant due to the extreme difficulty we had in getting the product to install in the first place. Any suggestions would be most welcome.
