I recently installed this application on my computer, and it works normally. I don't have any kind of errors. Therefore, I suggest you to reinstall WebSlide Browser. First of all, go to Control Panel > Uninstall a program > search there WebSlide Browser > right click on it > and press uninstall. Next, go its official website and download this tool again (you can also download it through Software Informer application's page). After the download is complete open the setup file and start the installation process once again.
