Error 1921 When Upgrading from Client Security 10 to Endpoint 11
I get this message while trying to perform the upgrade as stated in the subject:
Error 1921. Service Symantec Event Manager (ccEvtMgr) could not be stopped. Verify that you have sufficient privileges to stop system services.
I have no other option but to click Cancel since retry does not work. The rollback the installer performs breaks Client Security Firewall after reboot. So I have to uninstall/reinstall that.
I manually stopped the service before trying the install with the same results.
The computer is a Dell Latitude D620 Laptop. I have not had this problem on a desktop. I've also done the upgrade on a Latitude D610 without any issue.
