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 Web site.
Make sure you have the Microsoft Visual C++ 2010 Redistributable Package installed on your system. The package is available at the Microsoft Download Center. 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.
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.
The zipped installer consists of a zipped package containing a standalone installation application. To install from this package, unzip the installer, and then run the installation application.
The MSI installer is an installation file that can be used with the installer included in Windows 2000, Windows XP and Windows Server 2003.
See Section 4.1.1, “Installing the Windows Connector/ODBC Driver Using an Installer” for the steps to complete the installation with either of these installers.
The zipped DLL package 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 the steps to complete this type of installation.
An OLEDB/ODBC driver for Windows 64-bit is available from Microsoft Downloads.
