So where is EViews with respect to Office 2010 compatability

I'm particularly interested in 32-bit Office 2010, but others may be interested in 64 bit.

Can we assume the "New support for reading Microsoft Excel® 2007 XLSX Files" referred to on the website also applies to 2010 files?

Yep, EViews should still read 2010 .xlsx files.

The Excel add-in will work on 32bit versions of Excel, but not on 64bit.
