The Windows Explorer Client no longer automatically responds to adding a new DocuWare Desktop connection or switching from one connection to another. This was changed retroactively from DocuWare version 7.10 in conjunction with the latest version of the Windows Explorer Client.
If you have several DocuWare Desktop connections, first select the desired connection under DocuWare Desktop Apps > Connections. Then synchronize the Windows Explorer Client with the corresponding DocuWare system via the Restart / Update Settings option in the context menu of the Windows Explorer client.
