SSIS Package For Unzip files through Job

Hi,

I have created a job that will execute a SSIS package which will unzip some zip files. For unzipping we are using WinZip. In the package I have used a .Net script task for unzipping. This script is using WZUNZIP.  When I am executing the package directly it is unzipping all the zip files. But when I am executing the job that will execute the SSIS package for unzipping it is going on with the execution and not unzipping the zip files. So finally I stopped the job.

Can you please help me to resolve this issue?
