A friends computer (XP Home SP2) would not access the internet after Windows Update, when ZAPro (ver 6) started it would complain a lack of Root Certificates. I had to disable the ZA service and zlclient.exe in msconfig to enable internet access again. There are no available root certificate updates on Windows Update.

Attempting to uninstall ZAPro brings up the same error messages about possible lack of Root Certificates.

Attempting the same from Safe Mode brings up the same error messages.

How do I solve this or ultimately get rid of ZAPro in such a case?

Thanking you
