My version of Microsoft Office 2011 is suddenly acting as though I'd just installed it, demanding the 25-character key that I got five years after I I downloaded it. So, there's no disk/packaging to look for, and I can't find my electronic receipt. Ideas, anyone?
I've been out of the iWork loop for a long time. I realize Numbers '09 pre-dates Office 2010, but will it view XLSM files. I've found statements online indicating both that it does and does not do that.
All I want is to see the spreadsheets accurately, not work with them.
