Zone Alarm help

I cant seem to install Zone Alarm. I try installing  the latest version, but the install dialog box never opens. It tells me that it can't load the DLL library becuase "vsutil.dll" cant be found. I download another copy of the file and put it in my windows/temp/ folder, but when i try and do the install it tells me that dllregistersserver entry piont cant be found. what should I do?
