While trying to install Tableau, I'm getting the following error:
0x80070666 Another version of this product is already installed. Installation of this version cannot continue.
Try the following:
Computer -> Uninstall or change a program, find Tableau and remove it
Go to the drive where you install the Tableau and delete the folder (If you are using Windows try the following path: C:\Program Files\Tableau or C:/Program Files (x86)/Tableau). This is because even if you removed the program, there are still some remaining files stay in the Tableau folder.
Hope that helps!

I have been following this video to install the linkage between postgreSQL and C++ (https://www.youtube.com/watch?v=qDiC1Wja6Og), and after following all the steps, i get this error: "The code execution cannot proceed because LIBPQ.dll was not found." even though i went into the postgreSQL directory and found the file. I have no clue how to fix it, i've tried reinstalling postgres and i've restarted my pc each time it was needed. Any clues or solutions would be appreciated thanks
Try put libpq.dll into directory of your project build also you need to add
libeay32.dll,
libiconv-2.dll and
libintl-8.dll.
You can take all these libraries from Postgres installation
|---app.exe
|---libpq.dll
|---libeay32.dll
|---libiconv-2.dll
|---libintl-8.dll
or add path to libpq.dll into the path environment of your os
I have some trouble when I want to add a database.
_dataBase = QSqlDatabase::addDatabase("QPSQL");
After calling this method I have an error:
QSqlDatabase: QPSQL driver not loaded
QSqlDatabase: available drivers: QSQLITE QMYSQL QMYSQL3 QODBC QODBC3 QPSQL QPSQL7
I include to PATH variable paths to:
PostgreSQL\9.3\bin
PostgreSQL\9.3\lib
PostgreSQL\9.3\include
Also I copy folder sqldrivers to Debug folder. Also tried to copy dlls drom this folder to Debug. Doesn't work either.
I came here googling because I had the same problem in Windows.
In my case to solve the issue I had to install PostgreSQL for Windows 32 bits since my Qt target was MinGW 32 bits.
Additionally, I had to add the PATH to the PostgreSQL bin and lib directories so Qt could find the right .dlls.
#SET PATH=C:\Program Files (x86)\PostgreSQL\9.6\bin\;C:\Program Files (x86)\PostgreSQL\9.6\lib\;%PATH%
The PATH can be set before launching Qt Creator or using the Qt Creator itself via the Build Environment in the Projects pane.
Add the system variable QT_DEBUG_PLUGINS=1 if you want to get full information of why the QPSQL driver has not been loaded.
Probably you will discover that Qt is not able to find it. Copy and paste the output here to know what exactly happens.
Use depends.exe on qsqlpsql.dll and found that this dll need libpq.dll from PostgreSQL\9.3\libfolder. Add libpq.dll to Debug folder and it works:)
Try pip install PyQt5 event if you already installed it using conda or installer. It helped me.
I got same problem with deploying Qt application (windeployqt didn't help). I had to copy more .dlls (libcrypto-1_1-x64.dll, libiconv-2.dll, libintl-8.dll, libpq.dll, libssl-1_1-x64.dll, libwinpthread-1.dll) from postgreSQL bin path (c:\Program Files\PostgreSQL\12\bin) next to .exe file (according to dependency walker).
I'm new to MongoDB. I did my first install last week on a Linux machine and after I completed the install, I realized that I executed the install from the wrong folder/directory. Can I just move the installed files in that folder to the correct desired location where I want MongoDB to reside? I'm not familiar with all that happens during install, so I have no idea if install files are marked with an install home directory, or if other configurations occur that would result in MongoDB failing if I moved the files. Any help appreciated...
Thanks
Hey guys i have been trying to download it from the below link
http://www.enterprisedb.com/products-services-training/pgdownload
But once i download it, and try to run the set up it is giving me an error saying
An existing data directory has been selected but its neither empty, or a recognizable date directory,I tried changing the path on which it has to be downloaded it is not letting me do so
I'd recommend trying a package manager such as brew. Once you have it installed simply:
brew install postgres
Disclaimer: I have no experience with Postgres on Mac (or with a Mac at all).
The installer will create a directory where PostgreSQL stores all the database data and information. Without this so called "data directory" PostgreSQL does not work.
This data directory has nothing to do with your download directory.
Apparently you are pointing the installer to a directory that already exists and contains some data (not necessarily Postgres related data).
When being prompted for the "data directory" during installation you have to select an empty directory.
I don't know if the selection dialog of the installer will let you create a new directory, so you might want to create that directory manually before starting the installer.
Recently had this issue after attempting a reinstall of PostgreSQL on macOS 11.6
Removing the contents of the /Library/PostgreSQL/14/data directory seemed to resolve the issue and was able to successfully reinstall
I want to write application which uses Postgresql as DBMS.
To write client application do I need libpq library and header files?
If yes where I would get libpq library and header files.
Libpq is included in the full PostgreSQL source code. You can use just libpq without the rest of PostgreSQL, but must download the full package.
You can download it from the PostgreSQL Downloads page.
Once you extract the full package it is inside src\interfaces\libpq.
The PostgreSQL installation guide details how to install only the client libraries in the Installation section, under Client-only installation.
Libpq documentation is also available.
In postgresql sources, src\interfaces\libpq.
And yes, it is possible to compile only the libpq.
get the lipq from repo, {for debian} :
sudo apt-get install libpq-dev
I was also facing this issue but didn't got a clear answer:
This issue clearly states that while installing diesel-cli system is not able to locate libpq.lib
First of all you should have a Postgres installed on your machine.
Also diesel require visual c++, thus download and install it if not already, the size of setup will be ~5gb.
Once above installations are done you need to setup environment variables:
In my case path of Postgres installation is C:\Program Files\PostgreSQL thus add 2 environment variable path under User variables add new in Path where your libpq.lib is located in my case it is available in both C:\Program Files\PostgreSQL\12\lib and C:\Program Files\PostgreSQL\12\bin
Once this is added create one more environment variable PQ_LIB_DIR and set path as shown below
Note: Once done re-trigger the installation command in a new cmd window
Source: pq-sys and github-solution
For Windows users, it's in (version may be different)
C:\Program Files\PostgreSQL\11\lib
There you find libpq.lib. Provide this directory to Linker input.
Don't forget to include C:\Program Files\PostgreSQL\11\include directory for include directories.
I fix this problem reccently. This is a solution if you don't want to install Postgres in you windows.
At first, you need download Postgres Binaries. The version I download is 13.6, but it's seems like any version is fine.
Unzip the zip file.Copy libpq.lib from pgsql\lib to shomewhere like C:\Program Files\Postgres\lib.
Execute the following command in cmd window.
setx PQ_LIB_DIR "{where_you_copy_to}"
Open a new cmd windows and install diesel_cli
cargo install diesel_cli --no-default-features --features postgres
In linux vertify you get the libpq.
1st, there is an app: pg_config: https://www.postgresql.org/docs/current/app-pgconfig.html
after you found out the pg_config absolute bin path.(if you installed multi version of postgressql) Then You can get
--includedir
Print the location of C header files of the client interfaces.
--libdir
Print the location of object code libraries.
Then try to compile/build some example code: https://www.postgresql.org/docs/current/libpq-example.html
Some common failure example: https://www.postgresql.org/docs/current/libpq-build.html
You can install Postgres locally from https://www.enterprisedb.com/downloads/postgres-postgresql-downloads but select only "Command line tools" for install.
After that, you can found libpq.dll in C:\Program Files\PostgreSQL\15\bin
