Ok, I unistalled everything and cleaned registry. Now I got at phase 4 this error which I usually solved by running kernel manually. An error occurred while processing option SAP NetWeaver 7.0 including Enhancement Package 2 > SAP Application Server ABAP > MaxDB > Central System > Central System( Last error reported by the step :Error during execution of command identifier 'XSERVER_STOP' : MaxDB Software must be installed before this class can be instantiated!).
