Hello Maude,
Thank you for your message.
Do you mean that you want to disable the update removed in the Viewer settings? If this is the case, you can do so in the
Viewer Options -> Update tab. If you want to distribute this setting to your other Viewers, you can do so by copying the Viewer configuration file
config_4.xml located in the folder
C:\Users\YOUR_USERNAME\AppData\Roaming\Remote Utilities Files\ - replace the original file for other Viewer with the one that you've copied from already configured Viewer and that should update their settings as well.
Hope that helps.
