Hi Dawa,

Check installation folder for MSXML SDK. On my system I have C:\Program Files\MSXML 4.0\doc folder, which contains xmlsdk.chm file. If it is not there, you may need to rerun setup, perhaps help file installation is optional and you didn't chose to install it.

when I apply it to my schema file. My schema has a namespaceURI. The error says "OLE Error code 0x80020003: Member not found".

I don't know why you are getting this error. The following code uses XML Schema with a Namespace, it doesn't report any error for me:
