Hi every one
I want to upgrade my current OS(Win Vista Ultimate) to Win 7 Ultimate.
After checking for compatibility,a error which says "You must uninstall Zone Alarm" appears,but "ZONE ALARM IS NOT INSTALLED ON MY OS!!!"
I decided to use "Zone Alarm Removal Tool",but after running this program,this error occurs:
You are not authorized to remove the client from this machine
Reason:The version installtion doesn't have a password set.
A password is necessary to validate that the clean up is authorized

How can I solve this problem?
(I just want to UPGRADING to win 7 not have a new windows beside win vista)
