Important Information

The parameters for agent installation have been updated as follows:

  • “/folder=first folder\second folder\and another subfolder”
    The folder(s) will be created if they do not already exist. The remote client is registered within this specified folder. Important: the entire parameter must be enclosed in quotation marks.
  • /silent
    Runs the remote setup fully automatically without prompts or any user interaction. The installation process is visible. In this case, "C:\Program Files/fastviewer Remote-Service" is used as the installation path.
  • /verysilent
    Runs the remote setup fully automatically without prompts or any user interaction. The installation process is not visible. In this case, "C:\Program Files\fastviewer Remote Service" is used as the installation path.
  • /replaceexisting=true
    The remote client setup can take over a client that is still registered on the tunnel server if the setup is executed with this startup parameter. (The client must have the same FQDN as the previous installation.) This feature makes it possible to keep the position in the respective folder of the remote client overview as well as any previously entered information (for example, during a reinstall).
 

New Features

FastViewer ARM Support (Agent installer and Instant Meetings)

What's New

FastViewer Remote Agent and Instant Meetings now run directly on modern ARM processors, delivering a fast, smooth, and power-efficient remote support experience.

Why It Matters

This update ensures complete functionality across unattended access, UAC prompt management, multi-monitor setups, clipboard sync, file transfer, etc.

Impact

Unified Architecture Deployment: Installers (.exe / .msi) automatically detect host architecture (x86, x64, or ARM64) and deploy the appropriate binary.

Support for Multiple Agents on One PC

What's New

It is now possible to install multiple FastViewer Agents with different serial numbers on the same device. For new installations, the serial number is now displayed in:

  • Installation folder
  • Tray icon tooltip
  • Registry entries
  • Windows services
  • Settings.xml

Why It Matters

Simplifies identification and management of individual agent installations on systems running multiple FastViewer environments.

Impact

Improved administration, troubleshooting, and maintenance of multi-agent deployments.

Prerequisites

Full support is available for new installations or higher only (>=3.34.0020).

Notes

  • Upgrades from older versions may not display the serial number in all locations.
  • Legacy 3.33 Installer/Uninstaller logic stops any running FastTray instance.
  • Downgrades from version 3.34 to version 3.33 (or older) are not supported and will be blocked (an entry will be written to the FastViewerService.log).

LogViewer: Enhanced Access Dialog Logging

What's New

Additional access dialog events are now logged in LogViewer on supported client and server versions.

Why It Matters

Provides administrators with greater visibility into access-related events, making troubleshooting and auditing easier.

Impact

More detailed client log data is available for analysis.

Prerequisites

FastViewer Desktop 3.34.0020 or later. Supported On-Premise WebConference Server versions 5.3 or higher.

Improvements

  • The FastViewerServiceLog.txt could contain a large number of "notify activity to watchdog" entries, making the log harder to read. These entries are now hidden by default and will only be logged when WatchDogLogEnabled is set to true (settings.xml: default=false).
  • Improved keyboard input handling (including special characters) in Hyper-V (VMConnect) and RDP sessions.
  • General usability and stability improvements.

Bugs Fixed

  • Fixed a connection fallback issue in WebRCConnection when proxy-based cloud connectivity failed.
  • Identified and resolved two performance issues that could occur during WebRCGuiApp startup.
  • Fixed an Secure Advisor "action on connection end" problem.
  • Fixed an issue where delayed reboot requests from the M42 FastViewer WebConsole were executed immediately instead of after the configured delay.
  • Additional bug fixes and stability improvements.
