If your Client Manager has invited you to use DataShare and selected the scheduled upload function the DataShare connect application will not automatically remove itself from your desktop when your data upload has completed.
To enable scheduling to work the DataShare Connect application must remain installed on your desktop so that it can automatically perform an upload on the next scheduled date set by your Client Manager.
If you do not want the DataShare connect application to remain installed talk to your Client Manager and ask them to remove the scheduling option form your Engagement.
