About Service Releases
Jiwa 7 Service Releases are cumulative, and later Service Releases supersede earlier Service Releases.
This means you only need to install the most recent Service Release to obtain all the fixes of previous Service Releases. Installing a later Service Release will automatically remove older Service Releases.
Installing a later version of Jiwa will also remove any service releases for previous versions.
How to remove
The Windows Control Panel Add/Remove programs - View installed updates lists the updates installed and provides a way of uninstalling a Service Release.
The appearance of the Service Release in the Installed Updates list is also the method of indicating if the Service Release is installed.
