Today I finally decided to update Zone Alarm from version 65.737.000 to 70.337.000.
I've put it off this long because when installing the update it informs me that because of a conflict, I must first uninstall my Computer Associates AV.
I decided to do so today as my subscription would be running out soon and I wanted to try Norton AV.
After uninstalling, CA AV said to restart my computer for the uninstall to complete.
When Windows restarted (XP Pro) I got this dialog box.
zlclient.exe - Unable To Locate Component

Operating System:Windows XP Pro
