Can not start 1C:Enterprise 8.3 Server Agent Service

During installation of 1C:Enterprise Server I got an error message:
"Service 1C:Enterprise 8.3 Server (x86-64) Agent failed to start. Verify that you have sufficient privileges to start system services". Tried different options but nothing seemed worked. So, I just ignored and finished installation. Now I have 1C:Enterprise 8.3 Server (x86-64) Agent Service installed, but I can not start it. When I try to manually start it I get a message "Error 1069. Service did not start due to logon failure". How to solve this problem?

Solved already. Question closed. Just needed to specify password when created USR1CV8 user.
