pgAdmin v4: The application server could not be contacted.

[Richard Nielsen <lepluc@xxxxxxx>]

Hi,

I'm new to PostgresSQL and to this list! I have installed version 10 
64-bit (on Windows 7) I also used stackbuilder to install the ODBC 
drivers. The SQL shell allows me to logon to the server as postgres but 
when starting pgAdmin I get: The application  server could not be 
contacted. This a fatal error of course..... Any hint, tips or "Oh man 
you should have...." etc will be greatly appreciated.
