Connect SQL Server 64 bit to odbc 32 bit

09 October,2014 by Tom Collins

Question: I’m attempting to connect a SQL Server 64 bit linked server to a 32 bit odbc driver . The error message


The specified DSN contains an architectureThe specified DSN contains  mismatch between the Driver and application


I’ve read the post The specified DSN contains an architecture mismatch between the Driver and application  .   This doesn’t solve the specific problem , as there is no version of the Lotus Notes client driver which is 64 bit. 

I’ve tested attempting to set up a 64 bit DSN – but this doesn’t work because the set up is looking for a 64 bit Lotus Notes client – which is not installed.

How can I fix?

Answer: A SQL Server  64 bit can’t  connect to a 32 bit ODBC driver. SQL Server 64 bit can only link to the  64 bit library. Therefore , SQL Server 64 bit  only connects with a  64 bit ODBC Driver Manager library.

Some vendors haven’t invested on creating  ODBC drivers supporting both 32 bit and 64 bit.  In your case , you only have the option of a Lotus Notes client driver 32 bit.

Options to connect a SQL Server 64 bit to a 32-bit library

Your options are to a) contact the vendor and see if they have an unsupported version of the 64 bit    or b ) Investigate the possibility of using a bridge driver which allows a 32 bit to 64 bit transition.
