If Endpoint Upgrade Assistant fails to completely install, you need to manually remove the components that were installed before attempting to install it again.

Before you begin

Examine the Orion logs to determine why the installation failed. If ePO - On-prem is installed in the default location, the logs are located under C:\Program Files (x86)\McAfee\ePolicy Orchestrator\Server\Logs.

  1. Remove the extension .xml from C:\Program Files (x86)\McAfee\ePolicy Orchestrator\Server\conf\Catalina\localhost\UpgradeAssistant.XML.

  2. Remove the extensions directory from C:\Program Files (x86)\McAfee\ePolicy Orchestrator\Server\extensions\installed\EndpointUpgradeAssistant.

  3. Remove the OrionExtensions entry from the ePO - On-prem database table.

    Run the following SQL query:

    DELETE FROM dbo.OrionExtensions WHERE Name = 'EndpointUpgradeAssistant'

  4. (Optional) Restart the ePO - On-prem server only if you can't execute the first two steps (for example, if the files are locked).
