 Disconnected from Oracle Database 12c Enterprise Edition Release 12.1.0.2.0 - 64bit Production
With the Partitioning, Real Application Clusters, Automatic Storage Management, OLAP,
Advanced Analytics and Real Application Testing options

Now after looking into the same, I found that the above mentioned error is considered as a Bug - 25918275 which is normally seen in 12.1.0.2 Database Release.

For a quick workaround, please follow the below mentioned steps:

CREATE USER c##imadvisor IDENTIFIED BY secure-password DEFAULT TABLESPACE perm-tablespace TEMPORARY TABLESPACE temp-tablespace;

GRANT EXECUTE ON utl_file TO c##imadvisor;

After this, run @instimadv.sql

I hope this helps !!
