Error in running package with config file

Question

I have a 2012 package and it is referring to a config file which has the DB connectionstring. This config file was created through the "Package Configuration Organizer". When I execute the package through VS 2012, it works fine(Reads the config
from config file), but I get the below error when I run from DTEXEC. 
Command: 
C:\Program Files\Microsoft SQL Server\110\DTS\Binn>dtexec /f "C:\user\admin\Test\Pack1.dtsx /Conf "C:\user\admin\Test\P1.dtsconfig"
