Before installing the Connector/ODBC drivers on Windows:
Make sure your Microsoft Data Access Components (MDAC) are up to date. You can obtain the latest version from the Microsoft Data Access and Storage website.
Make sure the Visual C++ Redistributable for Visual Studio is installed (VC++ Runtime 2015 for Connector/ODBC 8.0.11 and higher, VC++ Runtime 2013 for Connector/ODBC 5.3). Use the version of the package that matches the system type of your Connector/ODBC driver: use the 64-bit version (marked by “x64” in the package's title and filename) if you are running a 64-bit driver, and use the 32-bit version (marked by “x86” in the package's title and filename) if you are running a 32-bit driver.
OpenSSL is a required dependency. The MSI package bundles OpenSSL libraries used by Connector/ODBC while the Zip Archive does not and requires that you install OpenSSL on the system.
There are different distribution types to use when installing for Windows. The software that is installed is identical in each case, only the installation method is different.
MySQL Installer (recommended): The general MySQL Installer application for Windows can install, upgrade, configure, and manage most MySQL products, including Connector/ODBC. Download it from http://dev.mysql.com/downloads/windows/installer/ and see the MySQL Installer documentation for additional details. This is not a Connector/ODBC specific installer.
MSI: The Windows MSI Installer Package is an installation file wizard that installs Connector/ODBC. Download it from https://dev.mysql.com/downloads/Connector/ODBC/. See Section 4.1.1, “Installing the Windows Connector/ODBC Driver Using an Installer” for additional details.
Zip Archive: Contains DLL files that must be manually installed. See Section 4.1.2, “Installing the Windows Connector/ODBC Driver Using the Zipped DLL Package” for additional details.
An OLEDB/ODBC driver for Windows 64-bit is available from Microsoft Downloads.
