It is possible to copy the Viewer's settings to another computer. In order to do that, please navigate to the Viewer C:\Users\[Your_username]\AppData\Roaming\Remote Utilities Files\
folder, and locate the file config_4.xml that contains Viewer settings. Please copy the configuration file and paste it to the same folder on another computer. Please note that the AppData folder might be hidden by default in which case you need to enable Hidden files and folders
in Windows Explorer settings.
Please note that the address book will not be copied to another machine along with the settings. In order to copy the address book please refer to this page
Hope that helps.
