Run Excel VBA Macro via AutoIt...

Hi Guys,

I used to use the following: 

$Excs = _ExcelBookOpen("C:\Us\Excs.xlsm", 0)
Sleep(1000)
$Excs.Run("MAIN_DS");

But after the Excel.au3 was re-write it doesn't work. 

I've had a look at https://www.autoitscript.com/autoit3/docs/libfunctions/Excel%20Management.htm mainly, [url=https://www.autoitscript.com/autoit3/docs/libfunctions/_Excel_BookOpen.htm and [url=https://www.autoitscript.com/autoit3/docs/libfunctions/_Excel_Open.htm but I can't seem to open the file nor can I find anything about how to run a macro.

Any advise would be very much welcome.

Following _Excel_BookOpen I get the following error...
 

I'm using Excel 2013 64bit.
