Ok, after more information, the situation we have is that I need to force my application to use the System DSN of the 32 bits version which is in C:\Windows\SysWOW64\odbcad32.exe. So, this is the focus. But, is this something I have control on in my application? The System DNS is already created. It is just that my application, by default, or any other .NET application BTW, uses by default the 64 bits version of the System DSN on a 64 bits OS. So, I have no idea presently what I can change in my Setup.exe to handle this.
