When Progress releases a Service Pack for a version, the update is applied to an existing installation that the Service Pack update wizard discovers on the target machine. To apply a Service Pack, navigate to the download page to get the appropriate package, and then unpack it on the target machine. The installer will provide a new installation with the 5.6 installation as well as its current service packs. An existing installation will upgrade in place with the updated service packs.
Note: A higher Service Pack for a version rolls up the features of all preceding Service Packs.
