Was the screenshot you posted just above made before you wiped the HD to try install, or have you Factory Recovered to Home Premium? If so use the Professional Product Key you received to Anytime Upgrade instead of trying to run it from the desktop. Type Anytime in Start Search box to begin process, insert key, Pro features unlock in minutes.
If you still have the wiped HD and you're trying to clean install Pro 64 bit, you'll have to follow the steps given here: UEFI (Unified Extensible Firmware Interface) - Install Windows 7 with - Windows 7 Forums
Hopefully you made your Recovery Disks or a Windows 7 Backup Image so that you retain the option to boot to restore Home Premium if necessary to do the Anytime Upgrade.
I will tell you that we recently had an epic thread with a Samsung laptop where the OP wiped the small recovery partition on the HD to reinstall, then found certain feature (touchpad gestures, cam advanced controls) wouldn't work right with the software on the Samsung Downloads page. But Samsung would not support going back using a Recovery Image stored externally because she wiped the HD partition required to run it - which we found out is remedied by saving Recovery to DVD instead so you have a self-bootable Recoverr. I would not tell Samsung you wiped the HD if you contact them as their "tech support" is a parody of how not to treat customers.
