Problem with invisibleutility removing AntiBot

"After several attempts @ removal of NAB so I can install NIS 2009, I get this Error 2753. The File 'Invisibleutility.exe' is not marked for installation and then Fatal error during installation. I know this is a resolved issue but cannot locate the resolution"

 

I have the same Problem installing Norton360 V3, but the solution in the "solved" message was send offline only. Could anyone post the solution here. Norton 360 V2 is already reinstalled on my computer!?

 

Thanks draw
