A couple of days before I have installed on my PC with Windows 7 Professional new version of PgAdmin (version 4). It worked fine, but today it loads slowly and then information window appears with text: «PgAdmin fatal error. The appllication server could not be contacted.». I restarted windows, but it doesn’t help. Is there any solution of this problem? Thanks.

I had the same issue. Try right clicking the PgAdmin icon and clicking «Run as administrator». Worked for me.

worked for me if I run PgAdmin as administrator.
Right click on the .exe file and run as administrator. It will work.

- in C:Users(your username)AppDataRoaming
delete folder pgAdmin
(AppData — is hidden folder) - run pgadmin with administrator.
Worked Fine for me
Previously it was showing Fatal error

I had to reinstall it, as Steve suggested in comments. Then it started working again.
It’s probably best to start with Ray Jowa’s solution — try right clicking the PgAdmin icon and clicking «Run as administrator».

This was odd, my PATH variable which had the python interpreter in it was somehow a factor, I do not completely understand though, right after I removed it everything worked, I will look further into it but so far I think that if you have python interpreter it might be the one causing the issue.
