I saw a statement on Amazon listing saying, "Rheingold replaced BMW ISTA-D soft." Can anyone tell me exactly what Rheingold or ISTA are exactly? I mean, is it something like a digital Bentley maintenance/repair manual, with diagrams and step by step on how to remove & replace, say, an alternator on my E70, etc.? Also, the listing says no VMware. What is VMware, and does that mean I don't need VMware, or that I will have to acquire VMware separately?
