Outlook on 7 x64 works fine, i'm not sure about the iphone sync.
I installed Office 2007 on my new Windows 7 x64, but 2007 worksheets open with Office 2010 Starter only,
and Office 2007 is not on the "open with" list. Programs with .xls extensions are set to open with
Microsoft Application Virtualization DDE launcher and there is nothing else to select
in Programs > Default Programs > Set Associations.
I cannot even find the Office 2007 program executable, although I can start it from the "Search Programs and Files"
