In order to fix the issue, uninstall the software using its uninstaller or Add or Remove Programs feature (Control Panel > Uninstall a program), run a registry cleaner to make sure that there are no leftover registry keys or toolbars in your system and download and install the updated version of the program. Once the installation process is finished, right-click on the Windows taskbar, select Properties and press the Customize button below the Notification area. Locate Badoo Desktop, select Show icon and notifications as behavior and click OK. After that, make sure that your security program and Windows Firewall don't block the software.
