Missing files from mysql odbc driver installer
Old, but for those searching, as me recently ;) Part of documentation section 4.1:


  Make sure the Visual C++ Redistributable for Visual Studio is installed. 
  • Connector/ODBC 8.0.14 or higher: VC++ Runtime 2015 or VC++ Runtime 2017 
  • Connector/ODBC 8.0.11 to 8.0.13: VC++ Runtime 2015 
  • Connector/ODBC 5.3: VC++ Runtime 2013  
  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.
