Re: Mcafee Installation Error (EPO Rolling back action)


Did you go through these steps?  Make sure your ePO install is at the same version as when your snapshots and backs were taken including hot fix.

As per KB66616 there are a few steps to follow.


To recover the ePO server
  1. Delete the ePO database on the SQL Server. If you do not know how to perform the MSSQL operation, see or contact Microsoft Support.
  2. If restoring ePO to the same system, uninstall ePO. Ensure that there is no ePolicy Orchestrator folder in the original installation path after the software is uninstalled.

    NOTE: Renaming the existing ePO folder and leaving the old directory in place might interfere with the new installation. So, we recommend that you remove the old directory completely.
  3. Reinstall ePO to the same version and update level as the server you are restoring.

    NOTE: You can verify the ePO update level. Look at the Version field in the backed-up Server.ini file (C:\Program Files (x86)\McAfee\ePolicy Orchestrator\DB\) and cross-reference it with article KB59938.

    IMPORTANT: You must reinstall ePO to the exact same directory path as the previous installation for this article to apply. If you do not, the initialization of extensions fails when the restore is complete. If the installation path is different, follow the steps in article KB71078 instead.
  4. Apply any additional updates, hotfixes, or POCs to ePO that had been previously applied. If you previously installed Policy Auditor 6.2 for use with ePO, install the same version of Policy Auditor, including any hotfix releases, that had been installed before.
  5. Stop and disable all ePO services:
    1. Click Start, Run, type services.msc, and click OK.
    2. Right-click each of the following services and select Stop:
      McAfee ePolicy Orchestrator Application Server
      McAfee ePolicy Orchestrator Event Parser
      McAfee ePolicy Orchestrator Server
    3. Double-click each of the following services and change Startup type to Disabled:
      McAfee ePolicy Orchestrator Application Server
      McAfee ePolicy Orchestrator Event Parser
      McAfee ePolicy Orchestrator Server
  6. Restore the database. See article KB52126 for details about restoring the ePO database using SQL Server Management Studio.
    Restore the database so that you do not require the ePO database configuration to be updated. For example, same name, host, port. Otherwise, you must update the restored DB.PROPERTIES file in C:\Program Files\McAfee\ePolicy Orchestrator\Server\conf\orion with the new information, before you start the server.

    IMPORTANT: In ePO 5.10 and later, threat event information has been split into its own database, so you must restore both databases. Carry out the restore process on both the main database and the events database.
  7. Rename the following folders (for example, rename the extensions folder to extensions_old), and then replace them with the corresponding folders that were backed up earlier in step 2:
    C:\Program Files (x86)\McAfee\ePolicy Orchestrator\Server\extensions
    C:\Program Files (x86)\McAfee\ePolicy Orchestrator\Server\conf
    C:\Program Files (x86)\McAfee\ePolicy Orchestrator\Server\keystore
    C:\Program Files (x86)\McAfee\ePolicy Orchestrator\DB\Software
    C:\Program Files (x86)\McAfee\ePolicy Orchestrator\DB\Keystore
    C:\Program Files (x86)\McAfee\ePolicy Orchestrator\Apache2\conf
  8. Start only the McAfee ePolicy Orchestrator Application Server service. 
  9. Access the core/config page of ePO and confirm the DB credentials if you are using ePO 5.3 or later, or if you are unable to access the ePO console. See KB69850 for detailed instructions on how to access the core\config page and update the DB credentials if needed.
  10. Attempt to log on to the ePO console. If you are unable to log on, review all steps performed in this article and ensure that they have been properly completed. If you cannot resolve the console logon issue, contact Technical Support for further assistance before you continue.

Re: Mcafee Installation Error (EPO Rolling back action)

We would need to know the error it has when it fails.  The install error.ini file will show the error and you can look for that in the msi log.
