The error appears when manually trying to start or restart the Data Extractor service.
This is usally caused by AntiVirus software (e.g. Sophos) blocking the Data Extractor services from running. Please add a folder\file exception to your AntiVirus software for this location C:\Program Files (x86)\Contact Group\Data Extractor.
The process on how to do this for Sophos can be found here https://doc.sophos.com/central/customer/help/en-us/ManageYourProducts/GlobalSettings/GlobalExclusions/index.html
