Microsoft Office

Hi Everyone. I've been struggling to download the 64 bit version of office 2016 professional plus, but it seems there's no way. The iso dowloader doesn't give the possibility to choose between 32 and 64 bit and just get the 32. Any suggestion?

Respectable forum I want to make a question: I own a Computer Acer Ferrari 1100 In which I had installed a registered copy with Product Key of Microsoft Office Enterprise 2007 32 bit. Unfortunately this computer has broken without giving me the possibility to uninstall this program. Now , as I have bought a new computer without hard disk in which I would like to install this program, I would like to know where I can download a new Product key of Microsoft Office Enterprise 2007 because the copy I own can be installed only on one computer. Sorry to have disturbed, thank to all that want to answer to my question , I get the occasion to salute all this forum.
