OcsPackage won't start without Admin Privileges

I Created an OCS package using the ocspackager

Now when i try to run it nothing happens.
When i run it as administrator the installation starts.
How can i fix this?

PsExec.exe is in the same directory as OcsPackager.exe

My configuration:
Agent setup file: "C:\OCSNG-Windows-Agent-2.1.1.1\OCS-NG-Windows-Agent-Setup
Certificate: Empty
Command: /Server=http://ocsinventory-ng/ocsinventory   (DNS refers "ocsinventory-ng" to the right IP address)
Label: Empty

User: Admin
Password: Adminpassword
