How should I create multiple instances of MS Excel 2013, in Win7 x64?

As you can see in "How can I get Excel's undo/redo functionality to work in a more traditional *per window* manner (and not for the entire instance of Excel)?", I expect when I open separate instances of Excel I have separate undo-redo lists, but in my MS Excel 2013 x64 (running in Win7 x64), all of the undo-redo(s) are in one list.

The first idea, coming to mind, is I am wrong and they are not different instances, though I am executing MS Excel from start -> all programs -> Microsoft office 2013 -> Excel 2013; then, the question is how should I create multiple instances of MS Excel?

Note that I cannot find the target of the shortcut files of MS Excel when I check right click -> properties -> shortcut. It also is not found in neither of program files(x86 or x64) -> microsoft -> office...

Does anyone have any idea to solve this?

If you double click an excel-file (without ALT) and immediately afterwards hold down alt, Excel will also popup the question "Do you want to start a new instance".
