Pgadmin 4 running error

When I have installed the program successfully but when I launch the program I get the following error:

I have googled and tried a few things that were mentioned, first I tried to right click on the pgadmin4 and select run as administrator. That did not work, and then I saw one one YouTube video talking about going into your services tab and making sure the server was running correctly. It was not so I selected start and thought that would fix the issue but it did not. I also uninstalled the 10.13 version and tried 12 but that didn't do anything either. Any other ideas?  

Thanks,
