I have a System DSN configured and test ok :

Microsoft SQL Server Native Client Version 10.00.2531

Data Source Name: xxx Data Source

I work on a windows 7 64 bits. The code in running in x86 mode.

In Excel, I can connect only to User DSN, the System DSN does not appear.
I tried also a use DSN, It works in excel but not in c#

I changed the permissions for the ODBC to everyone in regedit.

I use this connectionstring in the c# code : Data Source=xxx;Initial Catalog=yyy;Integrated Security=SSPI;

I have this error : ERROR [IM002] [Microsoft][ODBC Driver Manager] Data source name not found and no default driver specified

Any idea ?

Thanks in advance

I achieved to connect to the database without ODBC with that connection string:

 Driver={SQL Server Native Client 10.0};Server=xxx;Database=zzz;Trusted_Connection=yes;

Thanks !
