Downloading software hanged in 0%

Hello,

I am evaluating SCCM 2012.

I am using Windows Server 2012, SQL server 2008 Std all in one box. I am testing the installation of software and i am pushing 7zip 32 bit into a windows 7 machine. But, under the status of the software center states Downloading since yesterday and stuck in 0%. Thought. Attaching screenshot.

Thanks for your help,
