Some common problems with the Webinato Screen Sharing application or the Screen Sharing module may be remedied with the steps listed here.


If you are unable to share your screen while using the web browser Google Chrome, you may wish to review this article before following these steps.

Also, if you experience any display errors while viewing Screen Sharing either in a live room environment, or in a recorded AutpPilot, please read below for troubleshooting steps to help resolve the problem for future webinars.


  • Log out of the room and exit your web browser.
  • Uninstall Flash (with this uninstaller.) Then reinstall/update your Flash Player.
    Important: Even if you are NOT using Internet Explorer as your web browser to join the web conference room, the Flash Player for Internet Explorer MUST be installed for the application to function, in addition to Flash for non -Internet Explorer web browsers if you choose to use an alternative web browser such as Firefox or Opera.
  • Uninstall the application.
  • Reboot your computer and reinstall the Webinato Screen Sharing software. Download the installation file 
    • for MAC
    • for PC
      Alternatively, you can use an in-room link to re-download and reinstall the Webinato Screen Sharing Application, please click HERE for more information.


      NOTE: If you recently updated your computer's operating system, graphics card drivers or other core computer components, it is highly advised for you to reinstall the Screen Sharing application for optimal results. Changes to core components can greatly affect the performance of the Screen Sharing engine, and a reinstall is necessary for the application to see these core changes properly.
  • Make sure your web browser is up to date.
  • Adjust your firewall and/or antivirus to allow the application to run and access the Internet.
  • Clear your browser cache and Flash cookies.
  • Right-click inside the conference room, choose settings, click the tab that has a folder with a green arrow pointing inside. Move the notch to the right (Any position except for far left is okay).
    • If using Firefox, you may need to follow the instructions from here.
  • If asked to install and launch or just launch, click the launch button as the application was already installed in a previous step.
  • If the image is distorted or looks wrong, in the settings and options (the wheel/cog icon to the right of the Start Screen Sharing Button) you can try selecting or deselection the Use Image Driver option. Remember to Save the changed settings.
  • When using multiple monitors, ensure the monitors are in the correct order.
  • It may take over a minute for the image to initially appear inside the room. Wait two minutes for the image to appear.
  • Tight Encoding: This is a new option we provide to optimize and minimize bandwidth concerns. Viewers using lower bandwidth connections gets the benefit of this option. Please click here to see how to enable/disable and use/turn-off this function. If you encounter any of the following issues, stop and close the screen sharing completely. Then disable the tight encoding and save the settings. Restart the screen sharing.
    - Screen Share application does not connect or start the sharing suddenly (If this affects multiple organizers/presenters).
    - If some users are seeing a White screen in the shared area but not the actual image.
    - Any other color issues or distortions (Please report immediately to the Webinato technical support team).

 

We were able to identify application installation failures and run-time failures during the following scenarios.

  • If you are running multiple rooms on your computer, you can only use Screen Sharing in one room at a time! Screen Sharing from one Screen Sharing application to multiple rooms is not supported!
  • Application requires C: volume (partition) in order to create driver folder. 
  • The application will fail if, Program files or Program files (x86) - (if the machine runs 64 bit Windows, 32-bit programs are installed in Program File (x86) folder) - folder exists on volumes other than C: . The application will not launch in this instance and you may see a spinning circle in application launch pad. If you try to launch from the directory, it will still fail. In Windows error log (under Application category), you may see an error similar to 'System.IndexOutOfRangeException'.
  • Dependencies: 
    • .Net Framework is required (at least 1.1). On Windows XP, the application will fail when launched (with error message boxes). On Windows 8, you will be required to install a Windows feature -.Net Framework 3.5 (includes .Net 2.0 and 3.0).
    • Flash Player ActiveX is required to run application. If it does not exist, it will fail. You can install the ActiveX by navigating here with any browser (Installation is no longer required on Windows 8 and future versions).
    • If any installed component is missing, you will see .Net related errors (in debugger window). Please verify if all the components are properly installed and available in either C:\Program Files\omNovia\Projector (Systems running 32 bit Windows) or in C:\Program Files (x86)\omNovia\Projector (systems running 64 bit Windows).
    • If you are still getting application launch errors, please run Windows Update and make sure you have all current Security Updates installed. A missing Security Update could cause the projector to become stuck at connecting and to not function properly.
