Wait till CurrencyXchanger appears

Wait till CurrencyXchanger appears

After a while you should see CurrencyXchanger appear under Servers.  Once you see CurrencyXchanger appear, double click on it, or simply select it and click OK.

If CurrencXchanger does not appear after 30 seconds, then your 4D server may not be running. Once again, make sure you follow the instruction on how to restart 4D Server.

If you are 100% sure 4D Server is running and 4D Client cannot detect it under the TCP/IP tab, then make sure that your network connection is working. You can check that by trying accessing the Internet.  Sometimes Windows firewall configuration may interfere with 4D Client; you may want to ask an IT personel to check that.
