Can't execute pgAdmin4

Question

I installed Postgres9.6 ver And pgAdmin4 was installed together. But It is return message "The application server could not be contacted" When i execute pgadmin.

I tried to download and install pgAdmin4 from web. But have not changed anything.

I couldn't get anything Although I searched google about the message.

I Set System Path, And Postgres is running in my local. But pgadmin don't start up.

Do somebody know about this? Thank you.

update:

i found this question.

I think that is same my problem which got 3 good vote even if the message is different a little.

So i'm trying do that, But can't run setup.py.

I installed python. and run pgAdmin\web\setup.py with cmd as admin. But fail with message of

from flask import Flask No module named 'flask'

thank you.

If you are running windows then try this installer. https://www.postgresql.org/ftp/pgadmin/pgadmin4/v1.4/windows/ — Murtuza Z, Apr 20 '17 at 09:28
thank you comment, I tried that installer, but it is still happening. — Gs., Apr 21 '17 at 00:34
did you perform clean install ? I mean did you deleted all the directories created by pgAdmin & uninstalled pgAdmin4 completely from your system before installing it? — Murtuza Z, Apr 21 '17 at 04:38
n33rma // I didn't that, So i tried again after uninstall old version. But it was not solved. So i'm now using pgadmin3. But i will try again to install pgAdmin4 after all postgres and pgadmin delete. if it will work. i comment here. thank you — Gs., Apr 25 '17 at 00:27

I had the same problem with pgAdmin 4 1.5 on Windows 10 Professional. The solution was simply to delete %appdata%\pgAdmin which was created by an earlier version. On systems other than Windows, there probably is a pgAdmin directory in your user directory. Of course, all session settings etc. are gone after deleting this.

We got the same issue. so no need to any change in the file.

The following step we have resolve.

Search programs and files in start menu in cmd.
Right click cmd icon with Run As Administrator to open window command prompt.
Goto postgres directory C:\Program Files\PostgreSQL\10\pgAdmin 4\bin using cd command in command prompt or set environment variable
Execute pgAdmin4 command.

Let us know if you have problem again.

I got the same issue. I use PostgreSQL 10.5

Go to C:\Program Files\PostgreSQL\10\pgAdmin 4\bin
Right click on pgAdmin and choose "run as an administrator".

I echoes the same.

Restart your system after installation.
running pgAdmin4 with right click - System Administrator solves my issue. Nothing wrong with setup.
