Upgrade from SEP 12.1 to SEP 12.2 impossible: keeps asking for reboot
I am trying tu upgrade from SEP 12.1 to SEP 12.2 on a Windows SBS 2011 server. The installer keeps nagging me with the following remark:
"Symantec Endpoint Protection Manager has detected that there are pending system changes that require a reboot." and then asks me to reboot the machine. The messages comes back, even after reboots.
I read there are a number of solutions to similar problems when doing upgrades to 12.1. Can someone please tell me how to correctly handle this in my scenario with the never version?
