I am currently running Office 2007 on my 64 bit WIN 7 OS. It was on my 32 bit Vista system before I went to Win7, 64bit and seems to be runing ok; but I want to upgrade to 2010.
I went to Amazon to find an upgrade and was confused by the two options listed in the attachment.
Also, do I have to specify 64 bit? Can I upgrade at a cheaper, "upgrade" price, or do I have to purchase New; since it's whole version number upgrade?
