Click or select EPM System Uninstaller indicates the success or failure of the uninstallation. If any part of the installation failed, EPM System Uninstaller notes which assembly failed to install. Check the log files for more information about the errors. You can find the log files in EPM_ORACLE_HOME/diagnostics/logs/install. There is a log file for each assembly, named product-install.log; for example, hss-install.log.
