Following a message from Zone Alarm Pro, I downloaded update zapsetup_80_400_020_en.exe
When I try to run this it complains about not being able to access/run "vsutil.dll" in a temporary directory buried in "Documents and Settings".
I found a version of "vsutil.dll" in the Zone Alarm Programs directory, copied it to the temporary directory concerned, and reran the installer. It still complains about not being able to load vsutil.dll.
Has anyone else had this problem and know a workaround (apart from junking Zone Alarm altogether a going to comprehensive "Internet Suit" from one of the competitors) ?
