Then check Resource ID for the Controller Emulator in the CBF's Network Configuration as outlined in the document from Thwe Lin Han's answer. Make sure all Resource ID's in the Network Configuration are unique!
Then create a Controller Emulator instance with the Internet explorer as outlined in Thwe Lin Han's doument. Make sure to use the Resource ID you have configured for the Emulator in CBF's Network configuration. In the document from Thwe Lin Han it is 11, but use the one you configured in the Network Configuration instead.
If you now go to the Commissioning mode in CBF you should see the Emulator as "Version error,running".
