How can I update the VSP Engine Tools if I already have an older version installed?

If you already have a VSP Engine Tools installed on the target ArcGIS Server site and you would like to update the tools to a newer version simply use the same service folder and service name in the VSP Engine Tools post installer. The tools will be automatically updated/overwritten. If you would like to update the tools on a standalone server, please remove the tools via ArcGIS Server Manager before installing the new VSP Engine Tools version, otherwise the installation of the updated version will fail.
