Install SEP clients 12.1.RU 6MP5 errrors

Hi, ALL.

I have problems installing SEP clients 12.1.RU 6MP5 

in client server activity logs only two events

Time Stamp    Event Type
17.03.2017 19:17    The client computer has been added to the group
17.03.2017 19:17    Client has registered

in ruru log error : Enable to detect product 

In the SEP_Inst.log

MSI (s) (28:84) [22:12:37:841]: User policy value 'DisableRollback' is 0 

but no events (NOT MIGRATIONPENDINGREBOOT) OR SISFAILED=1

sep.log and sis_inst.log atached

Thanks/
