For Quickbooks hosted on Right Networks, one has to download the Web Connector file locally (to your local computer) and transfer it to the remote desktop using the File Manager service.
Please review this support article which should cover how to transfer the WC file to the remote desktop via the File Managers: https://filemanager.rightnetworks.com/Logon/Logon.aspx?ReturnUrl=%2f
Right Networks' remote desktop has a mandatory shut down after 30 minutes of activity. There is no option to modify this setting.
