In cases of updating to new service packs (SP x) and not to new versions (for example: updating 2020 to 2020 SP1) it is not necessary to run the StationWare update tool.
The StationWare update tool should be run when updating to a new StationWare version. This tool will automatically detect and run the required update steps. This updating procedure focuses on updating the StationWare database.
Running the tool in case of a service pack update will not cause any trouble, but it is not needed.
