After install BI, no server appears inside webMethods program group to start it. Also, no /BusinessIntegrator4/ directory is created, just one for the Repository Server and another for Document Dispatcher.
Have you any experience on that?
The problem might be your exe file which you are installing is not fully loaded.
So pls check that installation file or try to re-install it.
The problem is that you have not completely installed BI, as it has a client side, as well as the Process Monitor and Repo server. You must install the client side using the webMethods 4.6 Installer. What you have already installed is just the repo server and Process Monitor. Please follow the webMethods installation guide, and you will get everything you need for a complete install of BI.
