ODBC Connection not appearing SSIS

Question

I have a System DSN ODBC driver configured correctly on a server (the connection has been tested and works fine).

I've got an SSIS package, and when I try to create an ODBC connection manager, I can't find my ODBC connection in the drop down of data sources.

I've tried refreshing the list, closing and re-opening the solution, even re-creating the solution.

Has anyone experienced this before and if so how did you resolve it?

Many thanks

Most likely you have configured the system DNS on a 64-bit Windows, but the SSIS package runs in a 32-bit environment.

System DSNs will only be seen by the applications and tools which can use them -- 32-bit DSNs for 32-bit applications, and 64-bit DSNs for 64-bit applications. Source

For reference, the ODBC Administrator Window can be found in the following locations on a 64-bit environment.

1. C:\Windows\System32\odbcad32.exe (64-bit ODBC Administrator)
2. C:\Windows\SysWoW64\odbcad32.exe (32-bit ODBC Administrator)
