Problem solution with IE5.5

Hi, I wrote yesterday because I had problems transforming XSLT in some IE
clients that use IE 5.5 with only the first version of MSXML parser
(msxml.dll). I used MSXML2.FreeThreadedDOMDocument in Javascript. Yesterday
I tryed to found a good solution for these clients and I tryed to perform
the transformation with MSXML.DOMDocument but I need to pass parameters like
(addparameter function) and I found that I can't (or I don't know how to
pass them). Then I tryed to found a good solution to update only the IE
without the new parser and I found the MSXML 3.0 .cab File Redistribution
Package, I include the following code in my page and it shows me the XML
parser install dialog on the clients that haven't MSXML 3 (msxml.dll)
installed and after the XSLT transformation works fine. The only "problem"
is that he always ask to install the XML parser(the dialog always shows me).
Clients with an updated version of MSXML (IE 6) for eg. don't show the
dialog. I see that File Redistribution Package install msxml3.dll in
side-by-side mode. Can be this the problem?
Anyone knows a solution for this? I wan't to make work my clients so I find
I code solution for this. Not a client work solution.

Thanks a lot!! Urgent!! Another different solution is welcome too!

My code is:

<object id="MSXML3"
classid="clsid:f5078f32-c551-11d3-89b9-0000f81fe221"
codebase="msxml3.cab#version=8,20,8730,4"
type="application/x-oleobject"
STYLE="display: none">
</object>
