The version and build of the feature differ from the installed one

You cannot update a newer feature with an old one.

The LN UI and Connector for Web Services versions are packaged in WAR files (Web archives). If you copied the contents of the media to your system, you can later overwrite a .war file with another 10.4.x version and then run the installer again; this way, you can easily update your components. However if a newer InstallableUnit is needed for this war file, the installation may fail. Better is to always download the latest InstallableUnit from the FTP site and add or replace it in your Installation Area.

Note: If you copy a .war file to your system, you must also copy the corresponding InstallableUnit.info file. This file contains information on the version and dependencies of the UI.
