can't install company app Codename One windows phone

Question

I am successfully able to create and download build from CN1 server for Windows 8.

I am also able to unlock my windows phone (Microsoft Lumia 640 Windows OS 8.1) using 'Windows Phone Developer Registration' utility.

See below image.

But still I am getting this error, any suggestion please ?

For a testing sake, I created one dummy app just having textfields and even that simple one didn't work.

Thanks.

To run your app on windows phone 8, you have to do the following:

• You must be a registered developer.
• The phone must be registered.
• The phone must be connected to the host computer with the USB cable, turned on, and the screen must be unlocked.

To test apps on a Windows Phone 8 device:

• The Windows Phone IP over USB Transport service must be running. This service is installed and started when you install the Windows Phone SDK 8.0.
• The computer must recognize the connected device. A Windows Phone 8 phone is listed as a drive in File Explorer.
