>> oWs = CREATEOBJECT("MSSOAP.SoapClient30")

Thanks Sergey, using your notation it works.
But now I'm having some problems with creating the setup package:
I'm using VFP7's Installshield Express with the stk3redist.exe (which contains the *.msm redistributable files for the Soap toolkit 3.0) downloaded from MS site at the address

I include all the .msm files in the Installshield project, but on the client PC, when I try to use my application I got an "Interface not registered..." error (I think there's some dll which is not registered by the setup process).
If I manually install SOAP with the "full" setup (shipped with VFP) it works.

My question is:

how can I have SOAP automatically installed with my application setup (VFP7)? (and not run two separated installation setup)
