How do I connect my 32 bit app to a 64 bit System DSN?

How do I connect to a 64 bit system DSN from a 32 bit application? I get the error: ERROR [IM014] [Microsoft][ODBC Driver Manager] The specified DSN contains an architecture mismatch between the Driver and Application

OdbcConnection con = new OdbcConnection();
con.ConnectionString = string.Format("DSN={0}", _dsnName);

I've seen lots of posts where people use 64 bit to connect to 32 is there a way to go from 32 to 64 without redefining your ODBC Connection using the 32 bit app? c:\windows\syswow64\odbcad32.exe

A 'prefer32bit' exe, calling a 64bit dll. Solutions:

  1. CorFlags.exe SampleIntegration.exe /32BITPREF-
  2. Untick 'prefer 32 bit' in VisualStudio
  3. Compile to 64 bit

If you are able to you should consider compiling your app for Any CPU which will allow it to run as a 64 or 32 bit app depending on what HW it is run on.

For a very good detailed article about bitness differences see Scott Hanselman's blog post about this.
