VERSION: successfully installed the version below on windows 10.

ISSUE:
I am trying to open rpd file in online mode. I remember the password for that correctly ( made a note during installation). How ever I am also being prompted for USER: Administrator the password. when I enter the same password as Repository password it is giving message Authentication failed ( please refer to 2nd screen shot below). Is there a way to get to this password. I do not remember setting any other password during installation. Other than for RCU for the BIPLATFORM schema. IS there a some default value for the user Administrator... Please advice
