pgAdmin 4 not starting on Windows 10 64bit - postgresql

After a fresh install of postgres 9.6.0.1 for Windows 10 64bit I am not able to get pgAdmin 4 starting.
First it throws an fatal error message:
After OK, that message appears:
Is there anything wrong? because after OK - the program won't start.
What can I do to get pgadmin 4 running? What should I enter in Python Path and what in Application Path?

I have found now the problem, it was the Java installation on which pgadmin 4 depend heavily.
In Windows when installing Java 8 (Java SE in this case) you do not have to use JAVA_HOME and JAVA_JRE anylonger and you can install java with default path settings (with the version number)
So I installed JAVA SDK 8 32 and 64bit and pgadmin start up normally.
The PATH variable includes only C:\ProgramData\Oracle\Java\javapath, thats all and let you use allways the latest version of java you installed.

In my case, I installed pgAdmin 4 v4.25 (released Aug. 20, 2020) . It solved my issue .

I had the same problem. I think, the installation of Visual C++ 2013 Redistributable is the source.
I fixed it uninstalling pgAdmin 4 and installing it again.
It tried to install Visual C++ 2013 Redistributable again, but it was already installed and now it works.
Hope this helps.

Try to install pgamin 4.5.1, it works for me (w10 x64) pgadmin 4.1.5

After struggling for weeks with this problem I found a solution. In my case I have Anaconda installed and maybe it affects PgAdmin in some way, I don't know. In order to start PgAdmin I followed these steps:
Open cmd and move to C:\Program Files\PostgreSQL\11\pgAdmin 4\web
Run pgAdmin4.py with your Python distribution. I had to install several libraries.
In my case, an error appeared, I needed to change Line #32 of C:\Program Files\PostgreSQL\11\pgAdmin 4\web\pgadmin\browser\__init__.py. More precisely:
from flask_security.views import _security, _commit, default_render_json, _ctx to
from flask_security.views import _security, _commit, _render_json, _ctx
Last, I needed to edited line socket module from Python libraries, gethostbyaddr(name) found non-ASCII symbols in the host name of my computer, I don't have any of them :S. Well, I changed line #687
hostname, aliases, ipaddrs = gethostbyaddr(name) to
hostname, aliases, ipaddrs = gethostbyaddr("")
After all of these steps I run pgAdmin4.py again and it worked.
Hope it helps.

For me there was no way to make it work (pgAdmin4 Version 4.21 that comes with Postgres 11.8 on Windows 10 x64). I really tried every possible solution.
So I gave up and found pgAdmin3 Redux: https://tokavuh.com/pgAdmin3Redux/ that supports Postgres 11, too.
You will probably have problems starting it, because of missing dll's from some Visual C++ Redistributable version I could not find out, but fortunately you will find these missing dll's on https://www.dll-files.com, just search them there as errors pops up.

libtorrent error on Windows XP

I'm trying to run a program on Windows XP using libtorrent 1.1.5 (compiled via boost 1.65.1) and get the error "The entry point to the CreateSemaphoreExW procedure was not found in the KERNEL32.dll DLL.". On Windows 7+ this works fine. How can I fix this error?
UPDATE:
_WIN32_WINNT=0x0501 solved the problem
The answer is simple- you can not fix it. Take a look at the official documentation.
https://msdn.microsoft.com/en-us/library/windows/desktop/ms682446(v=vs.85).aspx
Minimum supported client: Windows Vista. You can try to download a kernel32.dll from windows 7 and put it into the application directory, but I doubt it would work.

pgadmin4 : postgresql application server could not be contacted.

I have installed PostgreSQL 9.6.2 on my Windows 8.1. But the pgadmin4 is not able to contact the local server. I have tried several solutions suggested here in stackoverflow, tried to uninstall and reinstall PostgreSQL 9.6.2 , tried to modify the config.py, config_distro.py, and delete the files in Roaming folder,i tried standalone pgadmin4 installation, but no success.However, in my local machine i am able to access the server using psql.exe and log as as superuser (postgres user). Can you please suggest any possible solutions to starting/running pgadmin4 ? Thank you.
I found the same issue when upgrading to pgAdmin 4 (v1.6). On Windows I found that clearing out the content inside C:\Users\%USERNAME%\AppData\Roaming\pgAdmin\sessions folder fixed the issue for me. I believe it was attempting to use the sessions from the prior version and was failing. I know the question was marked as answered, but downgrading may not always be an option.
Note: AppData\Roaming\pgAdmin is a hidden folder.
Start pgAdmin 4 as administrator.
Do the following steps:
Right click pgAdmin 4 icon
Select "Run As Administrator"
I had the same issue on Windows 10, with a new installation of PostgreSQL 10.
I solved it by including the path C:\PostgreSQL\10\bin ({your path to postgresql}\bin) to system environment variables.
To access environment variables: Control Panel > System and security > System or right click on PC, then > Advance system settings > Environment variables > System variables > Path > Edit.
I've been dealing with this for awhile (frustrating). So much that I have instructions on my desktop consolidating all of these ideas. Here is my magic combination to the solution:
Delete from App Data C:\Users\%USERNAME%\AppData\Roaming\pgAdmin
Add to Path Variables C:\Program Files\PostgreSQL\9.6\bin (I actually added it to both user and system)
Right click and start as admin.
You don't have to do this every time but when it gets out of wack try these steps.
What finally worked was downgrading to pgadminIII-v.1.22:
It seems in most of the cases Postgres trying to use information from previous sessions to find/connect the server and failing. Clearing out the previous session info helped me, it is a combination of 2 already mentioned answers above:
Navigate to Postgres session's folder
C:\Users\YourUsernameOrAdmin\AppData\Roaming\pgAdmin\sessions
Delete all the data from this folder.
Start PgAdmin in administrator mode.
Cheers!
if you are using Mac OS X here is a fix:
Open terminal and run this command
pg_ctl -D /usr/local/var/postgres -l /usr/local/var/postgres/server.log restart
and for other OS just restart your Postgresql server, it will solve
Then start pgAdmin4, it will start as normal

Deleting the contents of C:\Users\%USERNAME%\AppData\Roaming\pgAdmin directory worked for me!
I had same issue on windows. I had v1.6 installed as well as v2.0. Uninstalling v1.6 allowed me to login.
I had the same problem, but running it as an admin worked.
Have you recently installed a new version of pgAdmin ?
This issue (and the misleading message) is simply due to the fact that old versions of pgAdmin are unable to read the settings saved by a newer version of pgAdmin !
Make sure you're starting the right version of pgAdmin (your shortcuts are likely to point to the old version !) and/or uninstall the old version: the upgrade wizard doesn't do it for you !
Deleting contents of folder C:\Users\User_Name\AppData\Roaming\pgAdmin\sessions helped me, I was able to start and load the pgAdmin server
I had the same issue on the macosx and I renamed .pgadmin (in /users/costa) to .pgadminx and I was able to start pgAdmin4.
In Windows Just go to this path and clear it
,that works !!
C:\Users\%USERNAME%\AppData\Roaming\pgAdmin
I was able to solve the problem by changing the pgAdmin web interface port.
I believe this problem occurred on my computer because I have several other services consuming webs ports like qBittorrent, IDEJetbrains, etc.
Right-clicking on the pgAdmin logo near the clock is possible to configure it.
I Fixed it in windows 10 just running pgAdmin 4 as Run as Administrator .
If you use older postgresql version like 9.x and its services is running,PgAdmin 4 confused which server is base database.
So stop the service older version or new one.Run PgAdmin 4 as Administrator
Its worked for me
This is often a firewall problem. The firewall log then shows dropped packets between 127.0.0.1: and 127.0.0.1:, where the latter is the port shown in the Browser to get no connection with. This means, that the connection between pgAdmin client (high_port_1) and pgAdmin server (high_port_2) is blocked. Check your firewall log and if you find dropped packets like described, adapt your firewall settings accordingly.
If none of the methods help try checking your system and user environments PATH and PYTHONPATH variables.
I was getting this error due to my PATH variable was pointing to different Python installation (which comes from ArcGIS Desktop).
After removing path to my Python installation from PATH variable and completely removing PYTHONPATH variable, I got it working!
Keep in mind that python command will not be available from command line if you remove it from PATH.
I use the cmd prompt on Windows 10 with psql postgres postgres.
Then I launch pgAdmin4 and it works.
I had this problem with pgadmin4 v2.1 on linux fedora 27
Solved by installing a missing dependency:
python3-flask-babelex
Just click on that pgadmin 4 icon and run as administrator. Allow the access permissions. It will start locally.
I need to add this here because I've had several issues with this message. If you have recently upgraded to High Sierra you will find the latest (pgadmin 4.20) will keep appearing with the message "Application Server Could Not be Contacted". What this actually means on Macs is that python was unable to configure your environment in ~/.pgadmin
This directory stores all the things you setup and configure and even logs of what was ran on your user copy usage of pgadmin.
The way to fix this issue on High Sierra is down to sqlite3. If you look in that directory you'll see everything is stored in sqlite3 files.
When version 4.20 of pgadmin was released it was shipped with a version later than sqlite3.19 and the problem arises because High Sierra is shipped with sqlite3.19, so to fix this issue, you need to replace the old version of sqlite3 with the latest on your packager.
Now be aware, MacosX+ all use sqlite to store details for the majority of apps on your mac, so you'll need to make sure you do not just wipe the old version but you'll have to have both versions co-existing together in harmony to avoid anything major occurring on your mac.
1) download brew https://brew.sh/
2) update brew and upgrade brew to make sure it's up-to-date
3) brew install sqlite3
4) mv /usr/bin/sqlite3 /usr/bin/sqlite3.os
5) ln -s /usr/local/Cellar/sqlite/3.21.0/bin/sqlite3 /usr/bin/sqlite3
6) /usr/bin/sqlite3 -version (check version is later than 3.19)
You can now proceed to open up pgadmin as normal
Got this issue after I upgraded PostgreSQL 9.4 to 9.6. The 9.4 binary package had PgAdmin 3 while 9.6 came with PgAdmin 4. I resolved it after a clean installation (I completely uninstalled and reinstalled) of PostgreSQL.
However, under different circumstances, you could try running the pgAdmin 4 application as an Administrator. This should fix the error.
downloaded pgadmin 4 v2.0 and install it no problem atm on force installation. try it. that was solution for me.
For my case in Windows 10 for postgresql 10 version, it worked by changing SERVER_MODE to False in config_distro.py placed in web folder, as per these configuration settings: https://www.pgadmin.org/docs/pgadmin4/dev/desktop_deployment.html.
There are other settings mentioned in this answer (https://superuser.com/a/1131964) regarding python but I just changed SERVER_MODE and it worked.
Kill it in Windows Task Manager and then try again. It seems that there is some sort of a problem when accessing the server from different applications.
As for me on windows 2012r2 it's start to work only after I reinstall pgAdmin 4 to folder c:\pgAdmin4. With out spaces and any special chars.
And all so I give full permission to this folder in NTFS.
It worked for me after installing python2.7 for pgAdmin 4 v2
Happens mostly when you have multiple versions of pgadmin installed or while trying to upgrade. Even I tried everything from killing the "running PID on port 5432" to "changing the server mode". In my case I uninstall postgres and re-install it again on different port(5433).
Later, I opened it through cmd(right click on cmd and select "run cmd as an Administrator").

postgres odbc connection fails

I am trying to set up a new postgres odbc connection for an application.
This is done on 32-bit Windows 7 system. I installed latest postgresql 9.6 & psqlodbc 0905, and there were no errors. When I add the odbc connection string and test connectivity with postgres login, it fails with the following error:
Test connection failed because of an error in initialized provider.
Specified driver could not be loaded due to system error 182:
(PostgreSQL UNICODE, C:\Program
Files\psqlODBC\0905\bin\psqlodbc35w.dll)
Here's the connection string:
Driver={PostgreSQL
UNICODE};Server=127.0.0.1;Port=5432;Database=postgres;
Uid=postgres;Pwd=postgres;
I then installed Visual C++ redistributable packager versions 2008 and 2010 later. Rebooted the box. Still same issue.
Postgres + odbc + other installs were complete and without any errors.
This is getting too frustrating.
Please.. any ideas on how to fix this will be helpful.?!
Update: I have tested the following:
1. Installed older postgres & psdqlodbc version
2. Added psqlodbc path to PATH env variable at the start
3. Uninstalled standalone psqlodbc installs, and installed Stackbuilder from postgresql package to download and install psqlodbc component.
All of these have not not been any useful.
Final Update: I was able to fix this by using psqlodbc_09_03_0400. For whatever reason, other versions kept throwing error.
Apparently, according to the Microsoft index of error codes, error 182 means ERROR_INVALID_ORDINAL, which with the help of this answer I believe means that the postgresql ODBC driver is loading another DLL and trying to call a function within it that does not exist.
The most likely cause for this would be that the system is loading a wrong version of a DLL on which psqlodbc depends. In fact I found this thread where someone else was having the same issue (although back in 2005).
This could happen if you had installed some other package containing one of the DLLs that psqlodbc relies on, or maybe even another version of psqlodbc.
Try changing the windows search path to put the directory containing the psqlodbc drivers at the front to confirm if this is the case. If that works you might want to try to narrow the problem down until you can find exactly what DLL is conflicting, and if possible remove it.
It is also possible that there is some packaging issue with the psqlodbc package you are using - if that is the case you could try uninstalling that one and installing an earlier version.
Final Update: I was able to fix this by using psqlodbc_09_03_0400. For whatever reason, other versions kept throwing error.

Oracle - SQL Developer: msvcr100.dll is missing from your computer

Have installed 11g in Windows 7 (64 bit machine). Since the SQL developer wont work with 64 bit jdk.
Installed the 32 bit jdk1.7.0
and changed the ORACLE_HOME\sqldeveloper\sqldeveloper\bin\sqldeveloper.conf file SetJavaHome point to 32 bit jdk1.7.0.
Again started the SQL developer, but it throws msvcr100.dll missing. Find that the SQL Developer3.x supports at max jdk1.6.X.
Even tho the question is answered I would like to point out that downloading random DLLs from untrusted sources should be avoided.
If you are missing MSVCR100.DLL just install the correct redist for your platform.
32Bit: Microsoft Visual C++ 2010 SP1 Redistributable Package (x86)
http://www.microsoft.com/de-de/download/details.aspx?id=8328
64Bit: Microsoft Visual C++ 2010 SP1 Redistributable Package (x64)
http://www.microsoft.com/en-us/download/details.aspx?id=13523
Cheers,
Antonio Huete
These information is specified in ORACLE_HOME\sqldeveloper\releasenotes . So install the jdk1.6 and make the sqldeveloper.conf SetJavaHome point to this.
other workaround is go to jdk1.7.0 installed path jdk1.7.0\jre\bin copy msvcr100.dll and paste it into ORACLE_HOME\sqldeveloper\sqldeveloper\bin and again try start SQL Developer. It will start.
And The file is from
This file was downloaded from: http://www.dll-files.com
If you downloaded it from somewhere else, please let us know: http://www.dll-files.com/contact.php
Installation instructions:
Extract the .dll file from .zip file. We recommend that you extract the .dll to the installation directory of the program that is requesting the .dll.
If that doesn't work, you will have to extract the .dll to your system directory. By default, this is:
C:\Windows\System (Windows 95/98/Me)
C:\WINNT\System32 (Windows NT/2000)
C:\Windows\System32 (Windows XP, Vista, 7, win 8)
If you use a 64-bit version of Windows, you should also place the .dll in C:\Windows\SysWOW64\
Make sure to overwrite any existing files (but make a backup copy of the original file for safety).
Reboot your computer.
If the problem still occurs, try the following:
Open Windows Start menu and select "Run...".
Type CMD and press Enter (or if you use Windows ME, type COMMAND)).
Type regsvr32 .dll and press Enter.

I have just downloaded latest 4.1.3 version with jdk included - Windows 64-bit with JDK 8 included to my Windows Server 2008 R2 64-bit and faced the same problem. Could not start sqldeveloper.exe, because "msvcr100.dll is missing from your computer".
I did not want to install any additional bloatware, so what I did:
take msvcr100.dll from original download SQLDeveloper folder sqldeveloper\jdk\jre\bin
and copy it to Your's oracle installation bin folder, in my case - C:\oraclexe\app\oracle\product\11.2.0\server\bin
SQL developer started!
Edit (path)\sqldeveloper.sqldeveloper\bin\sqldeveloper.conf with Notepad++ or some other advanced text editor. Don't use Windows Notepad for this.
Locate the SetJavaHome variable. Replace "../../jdk" with your regular PC Java source. On mine it was "C:\Program Files\Java\jdk1.8.0_73".
The line looks like this when you're done:
SetJavaHome C:\Program Files\Java\jdk1.8.0_73
Save and exit.
I got this error while running Oracle JDeveloper.
I have copied the msvcr100.dll file from C:\Windows\System32 to C:\Program Files\Java\jdk1.8.0_261\jre\bin.
It worked for me. Also check the enviromental varibles settings.
The JDK needs msvcr100.dll to either be located in the same directory as sqldeveloper.exe OR already be installed on a Windows machine in a location defined in environment path variable. In testing SQL Developer install on various Windows 7 machines where I have other software installed (not a clean machine), the msvcr100.dll is installed on C: \Windows\system32\msvcr100.dll.
you may get it from sqldeveloper\jdk\jre\bin\msvcr100.dll(refer your installation dir)
I was facing the same issue and it worked for me.
For me the solution was to simply upgrade SQL Developer. When work changed over my laptop I copied SQL Developer between machines and I got the above error except for msvcr120.dll. I copied that dll from my old machine but then it needed another and then another. So I downloaded the latest version of SQL developer and the errors went away. It might not solve the issues for everything but I think updating to the latest version should be done before trying any of the other solutions.

Is there any recipe to successfully install PLPython in Postgresql 9.3 64bit or 32bit on Windows 64 bits?

running CREATE EXTENSION plpython3u gave me the error - The specified module could not be found even if the file is at the correct place.
After reading everything on the web, I tried to download another python version (3.2) as suggested and replace the dll.
Now I receive an error about a missing magic block: missing magic block HINT: Extension libraries are required to use the PG_MODULE_MAGIC macro.
I tried the same processes with a 32 and 64 bits version of Postgresql and both failed like explained.
Is there any solution to install that PLPython on a Windows 64 bits OS?
Worked for me (Windows 7 64-bit)
I installed Python 3.2 from here:
http://www.python.org/ftp/python/3.2/python-3.2.amd64.msi
Somebody screwed something up, so you need to do the following:
find python3.dll in C:\Python32\DLLs (or wherever you installed it)
copy python3.dll to python32.dll (like copy and paste it then rename it)
run create extension plpython3u in postgres
In case anyone has this problem with Postgres 9.4, use the steps in Neil McGuigan's answer, just with Python 3.3 (download link).
Make sure to use the version corresponding to your system (64-bit in most cases).
