Hi,

don't have a clear answer but some things you might want to check;

- is the CLSID_DOMDocument26 the constant for "MSXML.DOMDocument.2.6"?
- is the CLSID_DOMDocument the constant for "MSXML.DOMDocument"?
- Does the registry key "MSXML.DOMDocument.2.6" exist in your classes?
- Does the registry key "MSXML.DOMDocument" exists in your classes
(and does it point to the MSXML3 lib?)

Hope this helps,

Marvin Smit.
