This guide servers two purposes. One is to guide how to perform a new installation, and the other is to walk you through the un-installation and re-installation of the Webinato Screen Sharing application during troubleshooting.

  • If this is a first-time installation, skip the un-installation procedure and proceed to the Installing/Reinstalling the software section.
  • 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.

Dependencies: The following components are required to run the screen sharing application.

  • .Net Framework is required (at least 1.1). On Windows XP, the Screen Sharing 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 the 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 screen sharing launch errors, please run Windows Update and make sure you have all current Security Updates installed. A missing Security Update could cause the Screen Sharing application to become stuck at connecting and to not function properly.
