Hi Daniela,

The MS SOAP 3.0 is installed side by side with MS SOAP 2.0. IOW, the "MSSOAP.SoapClient" ProgID still points to MS SOAP 2.0. The 3.0 ProgID has '30' at the end.

oWs = CREATEOBJECT("MSSOAP.SoapClient30")

>local oWs
>oWs = CREATEOBJECT("MSSOAP.SoapClient")
>if vartype(oWs) <> "O"
>   * error
>endif

>
>I use VFP7 and I've included, in the InstallShield Express Setup, the SOAP SDK files (soap3_core.msm) and SOAP SDK ISAPI files (isapi3_files.msm).
>
>There are other libraries to include in the setup?
>
>In my development pc, obviously, work correctly, but in the pc W2000 Prof where I install my app, the createobject fails.
>
>Thanks in advance.
