Yeah, thats what I thought. Which is why I only use RVMintegrator for slipstreaming and nLite for the addon packs. The RVM integrator does not give me the option of putting the addon packs in any particular order. Provided that the packs don't share files, this shouldn't be a problem. But when you are integrating many packs, you get an increased risk of replacing newer files with older ones. There are so many different date formats. For example, I typicly integrate about 20 addons, which have these different kinds of date formats: mm/dd/yyyy dd/mm/yyyy yyyy/mm/dd dd-monthname-yyyy monthname/dd/yyyy Sorting them is a pain, not to mention the potential for user error. It can make those BSODs you mentioned hard to trace.
