After a day of working on trying to fix the oft-posted "system error, please reboot", I FINALLY got all of ZA uninstalled.
I've freshly downloaded from the zonealarms.com/trial site and when I run the instll program to download ZA itself, I get the error "downloaded file is not zonealarms installation" and a URL below it.

this was happening BEFORE I went through all the hassle of the safe mode deletions, and the only suggestion I got from tech support was to go through the safe mode protocol and try reinstalling.
Anybody know what is going on and what to do about it?
(other than demand my money back and try somebody else?)
