To resolve the issue, check the following:
- Make sure that you have the correct Internet connection settings. You may be having Internet connection issues because of incorrect DNS, Gateway, or Proxy configurations.
- Make sure to allow cookies on your browser. You may choose Low for Internet Explorer settings and Accept cookies from sites for Mozilla Firefox settings.
- When your computer is connected to the Internet through a proxy server, make sure that the system proxy setting is applied to the WFBS-SVC agent, WFBS-SVC_Agent_Installer.exe and WFBS-SVC_Downloader.exe.

- Open the Start menu and search for Control Panel.
- Click Network and Internet.
- Click Internet Options.
- Click Connections > LAN settings.
- Tick the Use a proxy server for your LAN (These settings will not apply to dial-up or VPN connections) check box, and then enter the correct proxy server address and port number.
- Tick the Bypass proxy server for local addresses checkbox and then click OK.
- Reinstall the agent.
- Clear the browser cache.
- Clear temporary files on the temp folder (%temp%).
- Use a different installation method.
