Hi
I'm guessing that your native SQL connections are 'trusted'
,so please set Protection Level for this package to "DontSaveSensitive" and try again run in 32-bit mode:
<drive>:\ Program Files(x86)\Microsoft SQL Server\110\DTS\Binn\DTExec.exe /F <your package>
and then in 64-bit mode:
<drive>:\ Program Files\Microsoft SQL Server\110\DTS\Binn\DTExec.exe /F <your package>
