After a few years of problem free upgrades of ZA I upgraded to 10.1.65.0. Running xp, ie8 and Avast AV.
Disaster, ZA will not load to taskbar and in folder Checkpoint/ZoneAlarm only 3 files are visable, diagnostic tool, readme and security. Vsmon.exe is running along with ISWSVC but no user programme visable. Tried to manually delete files as per support page and reinstall, but no luck, some files must still be there as ZA install said it was an upgrade ! Downloaded clean.exe, but this failed as my xp drive with ZA is D:/ and clean.exe defaults to searching C:/
Anyone have any ideas to resolve
