I was unable to install the x86 or x64 MySQL ODBC driver (v5.2.6) in my Windows 2008r2 server due to a reported missing module, the exact error was:
“Product: MySQL Connector/ODBC 5.2 — Error 1918.Error installing ODBC driver MySQL ODBC 5.2 ANSI Driver, ODBC error 13: The setup routines for the MySQL ODBC 5.2 ANSI Driver ODBC driver could not be loaded due to system error code 126: The specified module could not be found. (C:Program FilesMySQLConnector ODBC 5.2myodbc5S.dll).. Verify that the file MySQL ODBC 5.2 ANSI Driver exists and that you can access it.”
A little searching turned up a gem from another blogger, copying C:WindowsSystem32msvcr100_clr0400.dll to C:WindowsSystem32msvcr100.dll and then restarting the MySQL driver installation worked a treat!
