Hello Dana,
Thank you for your message.
This issue might be occurring if the Viewer configuration file was somehow damaged/corrupted (for example, by some antivirus software activity).
Please, try the following:
1. Fully exit the Viewer
File -> Exit.
2. Locate the file
config_4.xml in the
C:\Users\[Your_username]\AppData\Roaming\Remote Utilities Files\ folder.
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.
3. Remove the
config_4.xml file from that folder.
This will reset the Viewer settings. Your address books won't be affected by this action. However, you will need to register Viewer with your license key as described
here once again.
4. Run Viewer and try using the
Remote Printing feature once again.
Please let us know if the issue persists.
