How to you open multiple versions of Excel

I would like to open multiple versions of Excel, i.e. when I open multiple
files, I want each in their own Excel version, that way I can move the excel
windows on to different monitors and work on them both. Word does this now,
but I cannot figure how how to get Excel to do this.

thanks

Goto Tools->Options->view & check the option "Windows in TaskBar" so you can see the different files on task bar and can navigate using "Alt" &Tab.

Hope that was your query.

Thanks & Regards
