I'm using Win32::OLE in perl : $xl = Win32::OLE::Const->Load('Microsoft Excel'); then I test if scalar(keys %{$xl}) is zero : 
 if (scalar(keys %{$xl})==0) {
        return False;
    }
    else {
        return True;
    }

I tested this code in machine which supports Microsoft Excel 2003 it gives True, but when I tested the same code in machine where there is Microsoft Excel 2013 it gives me False! I also printed the scalar(keys %{$xl} in the first machine it gives 2023, in the second machine it is 0! Best Regards
