How do I open each workbook in it's own version of Excel?

Previously when I opened multiple workbooks each opened in it's own
application and I could view them seperately. Now they all open under the
same version and I have to select individually under windows. Please let me
know what I have changed.

Thanks for the response. I tried that and it still opens in the same window.
I need multiple windows.
