This procedure lets you launch a new process from another application using HTTP parameters. It applies to WorkflowGen versions 5 and 6. Follow the instructions below for your version of WorkflowGen.

Note: For security reasons, the impersonation feature is restricted to allowed users, as defined in the ProcessesRuntimeWebServiceAllowedUsers entry in the \wfgen\ws\web.config (version 5) or \wfgen\web.config (versions 6 and later) file.
