Check values for ORACLE_HOME in registry
Did you upload the Oracle Database 126.96.36.199 software (patch=p13390677) to the server and installed in new Oracle Home ?
i.e. Current Running Oracle Database Home=c:\oracle\VIS\188.8.131.52, New Oracle Home=c:\oracle\VIS\184.108.40.206.

Please check the /etc/oratab file; your database should have that entry.
