Update error: A product compatible with this update was not found
The error message "A product compatible with this update was not found" indicates that you are either attempting to update from a client machine or that you are already up to date to the update executable that you are running.
All product updates should be applied while directly at the server itself. Updates should never be applied from a computer other than the server.
Regarding already being up-to-date, you can verify your current DBA build in the software under (Help > About DBA Manufacturing). This should tell you whether or not the update you're applying has already been applied.
The last possible source of this error may be that the machine being updated has both a client installation and a full installation of DBA on it. If that's the case, you must uninstall one of them. A workstation should never have both a client installation of DBA and a full installation of DBA on it.
