XMLTOCURSOR() function internaly uses MSXML 3.0. You can try to reinstall MSXML 3.0 or download the latest version from http://msdn.microsoft.com/downloads/default.asp?url=/downloads/sample.asp?url=/msdn-files/027/001/772/msdncompositedoc.xml

>Whenever I attempt to use the XMLTOCURSOR command I get the error 'OLE error code 0x80040154 Class Not Registered.' I know I must be doing something wrong, but what? The trivial code I am testing is:
>
>select printer from printers into cursor cprinters
>x=CURSORTOXML('cprinters','cxml.xml',1,512,0,'sxml')
>=XMLTOCURSOR('cxml.xml','mycursor',512)
>
>cxml.xml does exist and appears to this untrained eye to be correct. Help!
