Unfortunately, we couldn't reproduce the issue with the "Fatal error" message appearing after updating Host to version 22.214.171.124. However, we've reproduced the behavior with three Host icons in the system tray that Peter have mentioned. Could you please provide us the Installation log files from the remote Hosts that you were updating? The installation logs can be located in the following folder: C:\ProgramData\Remote Utilities\install.log. You can send the log files to [email protected]. I'll forward the installation logs to our developers for examination.
The issue might be caused by the Viewer configuration file being somehow corrupted (for example, by some firewall/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. 4. Run the Viewer, try registering it with your license key again and see if this helped to resolve the issue.
In addition, please try updating your Remote Utilities installation to the latest 126.96.36.199 version - we've fixed a small bug related to the license key storage. For more information please see our Release Notes. You can update your installation via the Self-Update feature.
Could you please let us know what exactly view modes do you use? In addition, in case if you use Remote Utilities of version 188.8.131.52 or an older version, please try updating to the latest 184.108.40.206 version and see if this helps to resolve the issue with your remote screen scaling - starting version 7 we've added support for high DPI resolutions.
The latest version 220.127.116.11 is available for download on this page. You can also update your Remote Utilities installation via the Self-Update feature. When updating please make sure to update both Host and Viewer to the same version as the version mismatch might lead to performance issues or some features not working.
