ODBC Driver Missing / Not Listed

Though the installation of emissary RT appears to be successful, the driver may not show in the list of available drivers within the "Data Sources (ODBC)" application.  Please check the following:

1. Ensure you are using the correct architecture of the "Data Sources (ODBC)" application (Data Source Administrator).  On 64-bit systems, Windows has two versions of the Data Source Administrator for each architecture (32 and 64-bit). Emissary RT is a 32-bit driver, and must be accessed from the 32-bit version.  The 32-bit Data Source Administrator may or may not be found in administrative tools, but is located (by default) at "C:\Windows\SysWOW64\odbcad32.exe"
2. Ensure "Microsoft .NET framework" version 4.0 or greater is installed
3. If running Windows Vista/2008 or greater, ensure you choose "Run As Administrator" when executing the installer
4. If running Windows XP, ensure that service pack 3 is installed
5. If running Windows 2003, ensure that service pack 2 is installed
6. After installing emissary RT, ensure "Microsoft Visual C++ 2012 Redistributable (x86)" update 4 or above is installed.  If it is not, this can be obtained and installed manually from: http://www.microsoft.com/en-us/download/details.aspx?id=30679

For solutions 2-6, perform an full uninstall, then reinstall after installing any prerequisites.
