VB6 & Windows 7 Soap Issues??

I've been trying to get my VB6 app to work on Windows 7 desktop and have got it working all bar getting it work when it's called a web service via soap as per the code below:

Dim SoapObjectclient As New SoapClient
'Call the web service passing the built up xml string
Call SoapObjectclient.mssoapinit(WSDL)

It comes up with the error:

ActiveX Component can't create object HResult:1AD.

Any ideas?
