Mysql Driver Not Loaded Windows
You have downloaded MySQL Connector/ODBC (ODBC driver) from MySQL – Connector/ODBC. And when you’re trying to install it on Windows, you receive error message similar as the following:
Solution
MySQL Connector/ODBC requires Microsoft Visual C++ 2010 redistributable so you have to install it first.
Hi, I see tons of posts related to this. But, I still have the same issue after running through several of the solutions in these posts. I used the full path for the jar, and it's not an empty file. I'm running windows. Qt5.9.1 QMYSQL driver won't load. Ask Question Asked 1 year, 11 months ago. PyQt5 mysql driver not found. Installing Windows to flash BIOS, then reinstalling Ubuntu Is it possible to grow new organs through exposure to radioactivity?
If you want to install MySQL Connector/ODBC 32-bit version, you have to download and install Microsoft Visual C++ 2010 Redistributable Package (x86).
If you want to install MySQL Connector/ODBC 64-bit version, you have to download and install Microsoft Visual C++ 2010 Redistributable Package (x64).
After you installed Microsoft Visual C++ 2010 redistributable, you can try reinstall MySQL Connector/ODBC again, the issue should be resolved this time.
Added solution from a user, VCD:
For me, I am installing mysql-connector-odbc-5.3.6-win32.msi, Microsoft Visual C++ 2010 Redistributable Package (x86) doesn’t work for me. However Visual C++ Redistributable Packages for Visual Studio 2013 works.
You can find Visual C++ Redistributable Packages for Visual Studio 2013 at

I was facing the same issue and even 'Hồ Sĩ Sơn's solution didn't work. I then found out that I had installed a 64-bit version of MySQL and was trying it on a 32-bit version of Qt.
Copying the dll from the below location didn't work:

Instead download the 32-bit version of libmysql.dll from:
and the copy it to your mingw folder.
In my case, I had to copy the DLL to msvc2010 folder since I am using Visual Studio compiler:
Hope this helps. :)

I was able to resolve my issue using a combination of Hồ Sĩ Sơn, Ram, and Sumanth's posts (Thank you both).
Here are my exact steps:
Checked the version of Qt Creator that I am running by visiting Help -> About Qt Creator. I found that I am running the 32-bit version.
Now that I know what version I am running I navigated to the 32-bit version of the MySQL connector. This was found in C:Program Files (x86)MySQLMySQL Connector C 6.1lib.
I copied the libmysql.dll file found in that folder, and pasted it into C:Qt5.9.2mingw53_32bin since I am compiling with MinGW. Note that this is the 32-bit folder.
Restarted Qt Creator and rebuilt my project.
The steps that were challenging me were matching the x-bit version of Qt Creator, my compiler, and the driver, then restarting Qt Creator.
Hope this helps someone out there!
Qpsql Driver Not Loaded
I faced the same issue and resolved by below steps.
By doing 6 hours of research finally issue is resolved. I was using 64 bit windows 10, 32 bit Qta and 64 bit MySQL server.
QSQLITE and QODBC was working perfectly, but faced issue with QMYSQL.
Later I have downloaded 'mysql-connector-c-6.1.11-win32.zip' (if it is 32 bit QT)from https://dev.mysql.com/downloads/connector/c/ copied 'libmysql.dll' to QT path C:Qt5.9.3mingw53_32bin.
Wow. it was working perfectly.
Avag SargsyanI also spent about 2 days on this problem, here's how I solved it:
My setup:64 bit Windows 10QT 5.11.1 and QT Creator 4.7.1 32 bitBuilding a 64 bit app..
Download this zip file: mysql-connector-c-6.1.11-winx64.zipfrom this website:https://downloads.mysql.com/archives/c-c/
copy this file:C:.mysql-connector-c-6.1.11-winx64.zipmysql-connector-c-6.1.11-winx64liblibmysql.dll
into this directory:C:Qt5.11.1msvc2015_64bin
Note: change 'msvc2015_64' to whatever compiler you are using, though it needs to be 64 bit.
when deploying your app, copy libmysql.dll to the same directory as your .exe fileI hope this helps you same some time and frustration!
