Is there Vista x64 support for Office Live add-in?  If not, is that going to happen soon.  I notice MS has problems supporting its own x64 OS, that's why I ask.

Microsoft Office (and the Office Live Add-in) run on Vista x64 today.  Are you looking for some specific feature support in Office provided by the x64 OS that is missing?

Please reply with some more information about what you are trying to accomplish and I'll do my best to help.

I'm up and running right now with Windows XP Professional x64 SP2 - today is Saturday March 29th.  Can you please put this on the shelf until you can definitely advise if Microsoft Office Live will be ALSO available for my OS - it's XP Professional x64 SP2.  Then, contact me, please.  BTW, is "what's good for Vista x64 NOT good for Windows XP x64 or are they joined at the hip."

Thanks.
