I accidently deleted Cyberlinl Power2Go from my Vista Home Premium

I accidently deleted Cyberlink Power2Go V. 5 from my Vista Home Premium in my HP Desktop. It is not in the Recycle Bin. I tried System Restore at the Back date but it is not there. How can I recover my Cyberlink Power2Go V5 from my Recovery Disk.

Please Help.
Thank you
