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.
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").
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.
I spent several days trying to solve this, so I'm going to post both the question and answer for the next person.
In CentOS 7, mounting a folder shared by Windows 7 with the following command:
mount -t cifs //MyWindowsPC/SharedFolder $MOUNTPOINT -o user=$USER,uid=$USER,gid="`id -g "$USER"`",cache=none
resulted in Input/Output errors using parallel make (make -j), but not with sequential make. The files that gcc/g++ were unable to read changed with each attempt and occasionally gcc/g++ would note that the error was not reproducible. This led me on quite a wild goose chase as system logs showed very generic CIFS/VFS errors.
There is an issue on the Windows side of things. I tried a combination of suggestions from various websites. I haven't spent time to understand the solution, but I narrowed it down to just two Windows registry changes. I have tested that this fixes the problem on 5+ different Windows 7 machines sharing with several different CentOS 7 and CentOS 6.2 machines. Input/output errors disappear and accessing the share is fast. Here is the solution:
Go to Start and search for “regedit”. Open that and navigate to HKEY_LOCAL_MACHINE/SYSTEM/CurrentControlSet/services/LanmanServer/Parameters/. In that folder, change the “Size” parameter from 1 to 3 by right clicking it and selecting “modify”.
In the same folder, right click and select “new->DWORD (32 bit)”. Name it “SMB2” and ensure that it is set to zero (should be default).
Restart your windows machine and that should resolve issues compiling in the windows share.
I'm not sure that both changes are necessary, but I am sure that together they fix the problem.
I'm using 64 bit Windows 7. I have downloaded the latest version of Parse.exe and ParseConsole.exe into a folder. When I run ParseConsole.exe and key in parse new command I'm getting this error:
Error talking to the parse servers;please try again
When I key in the command parse help I'm getting info.
Am I missing something? Do I need to install any other plugins? How should I get it to run without errors?
I also struggled a lot facing the same issue.
I was however able to solve the same.
Download the CLI from the website.
Go here and check if you have same version of parse.exe as downloaded or else replace the older one with this.
copy both of the files ( parse.exe and parseconsole.exe) into c:\windows\system32 for 32 bit operating system and into c:\windows\syswow64 for 64 bit operating system
open windows power shell and run it as administrator , test all your commands.
It should be working fine now :)
