Idiot's guide for the OEMizer...that would be Tiermann
He made a help file for it recently. Have you checked the OEMizer thread?
component missing/not trusted...sounds like you have setup.dll problems. Those are beyond OEMizer, last I heard. In the kitchen is a tutorial by JBabey that deals with how to construct easy to moderate difficulty OEMs. If you're having setup.dll problems, you're deep into advanced material. Search for a thread by me about DLLInvoker - maybe it'll help you.
