I just picked up a new copy of office 2010 Pro and am trying to figure out if it will work properly on my Win 7 64-bit laptops, as in utilize the extra capability of the 64-bit OS. It says on the bar code strip "32-bit/x64". On the side I see at the end of the OS requirements, "or later 32- or 64- bit OS". Who can tell me if I have the copy that I need/want? I can't see the "version" designation listed anywhere on the box. It does say it's for Win 7 and works for Vista and XP. I'm not going to unwrap it until I know it will work as it should with 64-bit.
