SolvedI Need Help Using My New CD Key On Same Steam Account

So I have looked at a lot of pages and they say go to here HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Bohemia Interactive Studio\ArmA 2 OA in regedit which I do. Then I right click on the folder that has my key (arma 2 oa) then I click on permissions, advanced, click on administrator, and then they say select edit and chose deny in set value. I do not get an edit option. If you want a screen shot of what it looks like just say then I will pm you screenshot.

Make sure you have run ArmA 2 Operation Arrowhead first.
