Failed verifying signature for Package

Hi

We installed OCS NG Server, everything is working well except for Package Deployment.

 

When creating ZIP containing *.msi and install commands the logs shows the following error

COM SERVER => Sending fileGet request to URL <HTTP://*******.corp/download/1447858672/1447858672-1>

When I create a package and only specify a windows command like "shutdown /r /p" and deploy, it works 100% and returns SUCCESS.

 

Help would be appreciated
