Excel Instance Launcher
Right click an Excel file, and launch it in a new instance. Excel Instance Launcher allows you to open the selected Excel files in a new instance. Very handy if you happen to use Excel with any frequency. It works on any Excel compatible file-CSV's included-regardless of which version of Excel you use.
