Configuring Workflow Implementation System in Business Integ

When I try to configure the WF Implementation System, I am asked to give the install path to the Workflow System (as far as I think, the Workflow Client is meant, is tha right?) So far so good. But then, I’m asked the path to the Enterprise JVM and no matter what path I assign, there comes an error message (e.g. if I assign the path to the jvm of EI - as I did while configuring Enterprise Impl. System - bi_client.jar is missing, assigning the path to the lib-directory of wf server - where bi_client.jar is - tools.jar is missing). In the “BI WF Implementaion System Guide” this step is never mentioned!!

So which file to copy in which directory for making the system work?

Thanks in advance very much!
