Wildix Integration Service was available in the Scappman app catalogue. We need to have it back in the PMPC App catalogue, since Wildix Integration Collaboration App has a dependency with Wildix Integration service, so these two deployments have to be on a similar version level to function correctly. enableAutoupdate=false switch is mandatory, since auto update requires administrative-rights on the client and therefor is not usable. Inplace update of previous versions went successful with no issues.
