MS Office 2007 Excel files pdf conversion using Adobe Acrobat 7.1.0 Professional

Microsoft excel has different features and function. Actually I am new in ms excel and did not know about more excel function. But when I open my excel that time a pop-up notification was shown on my system screen MS Excel Has Stopped Working Error. So This problem wasted my time.

I don't think Acrobat 7 can recognize Office 2007 files; Acrobat 7 was released way before Office 2007.
