SSIS package fails in sql server agent, but not in

I have an SSIS package that runs fine in visual studio 2010, but as a job it sql server it fails when connecting to an ODBC database.

The project encrypts sensitive data with a password. This is because the proxy server isn't my account. It also happens to be the user that connects to the ODBC with a connection string. The job connects to a couple non-ODBC databases successfully before failing at the ODBC connection.

The project is set up to run in 32-bit mode, but strangely enough when I set it to 64-bit it'll fail at the ODBC connection.

All the servers are set to run with the current user except for the ODBC database, which has a connection string. Could this have something to do with it?

Here's the error message

Description: An ODBC error -1 has occurred.  End Error  Error: 2014-11-07 09:05:14.18     Code: 0xC0014009

Thanks in advance.

I was able to fix this problem by creating a 64 bit System DSN with the same name as the 32 bit one.

Task Manager's Platform column shows that my Visual Studio (devenv.exe) is 32 bit and that my SQL Server Agent service (SQLAGENT.EXE) is 64 bit. That explains it.
