Answer 1

The PK at the begining gives away it's a zip file. Coincidentally, xlsx is a special kind of zip file. Try to save the file as .xlsx instead of .xls and Excel should handle it correctly.

Given you're specifying Excel2007 as the format, you're getting an .xlsx file. If you need a .xls file, maybe you can use Excel2003 instead.
