Solution:-

1) Ensure that the following packages are installed on the OMS Server. If not install them.

• Microsoft Visual C++ 2010 Redistributable Package
• Microsoft Visual C++ 2012 Redistributable Package
• Microsoft Visual C++ 2015 Redistributable Package Update 3

2) Delete the <OMS_BASE_DIR>\gc_inst directory created during the oms configuration.

3) If the OEM installer is still running click on "Retry".

If not, execute following from command prompt:

    $ 13.5_OMS_HOME/oui/bin> ./runConfig.sh ORACLE_HOME=<13.5_OMS_HOME> MODE=perform ACTION=configure COMPONENT_XML={encap_oms.1_0_0_0_0.xml}

This should resolve the issue.
