I have ZAF version 6.0...installed. I get validation failed errors. There have been several posts on this difficulty, but I have not found a remover that is designed for Win 98. I have the file ZA cpes clean.exe and the fixit file. Both are for Win XP and above. There is probably a fix on AZ web pages, but have not found. Please give me a pointer to it. Am not able now to install ZA 7.0..., which I have in a backup drive. Thanks for your help.
