Error: Unable to connect to data source ''.ERROR [IM014] [Microsoft][ODBC Driver Manager] The specified DSN contains an architecture mismatch between the Driver and Application



Solution: check your Windows version 32 bit or 64 bits, use the obdc correct version

c:\windows\system32\odbcad32.exe or %WINDIR%\System32\odbcad32.exe
 

c:\windows\sysWOW64\odbcad32.exe or %WINDIR%sysWOW64\odbcad32.exe


Nota: Check if have created an odbc with 32 and 64 and just remove it (the cause of the error).
