>When I deploy the VFP COM object on IIS Server (running on NT 4.0), it prompt an error message "Cannot locate the MS VFP support library.". Should I need to deploy VFP runtime to IIS Server? Can I use VFP Wizard to create runtime setup file to deploy or have any simple way to do? Thank you very much ...

Yup, you need to deploy the VFP runtimes to the server running IIS. You can just copy the files needed, or you can create a very simple setup with just the runtimes (better).
