CCMaker won’t to make connection via my active Internet!

I was trying to install “Photoshop CC2017” on my system (Win10/Enterprise).

To do this, I had to run CCMaker first. But even while connected to the Internet, the program (CCMaker) said it could not connect to the Internet!

I turned off the antivirus (AVG), and Windows Firewall has no active blocking permissions for Photoshop or even Adobe.
I also ran CCMaker by right-clicking and using Run As Administrator. But I still get the same message.

What is the problem?
