The application has been discontinued which means you are using an application that isn't supported anymore. This is the reason you receive errors related to Internet connectivity. Right click the setup package or the executable file, then choose Properties > Compatibility. Make sure you choose Windows XP Service Pack 3. Right click the file again and launch it as Administrator. The error should disappear by now. However, if you still receive errors, then it means the software is lacking support for the operating system installed on your computer.
