NotesSQL driver

NotesSQL is 32-bit only. 
If your Windows 7 is 64-bit, that's the problem.

NotesSQL is 32-bit. When you use Administrative Tools in 64-bit Windows to view ODBC drivers, it only shows the 64-bit drivers.

You need to run a separate program to view 32-bit ODBC drivers. 
You need to run the 32bit odbc client which is here:
C:\Windows\SysWOW64\odbcad32.exe
