I've been searching for the past 2+ hours, and still haven't found anything that clearly answers the (often-asked) question: How to include .NET 3.5 in nLite? I'm just getting started with nLite, but I've gone through all the tutorials I can find (which are somewhat simplistic). I now understand how to incorporate service packs, define users, customize settings, etc. But how/where do I include .NET 3.5 (along with SP1)? Is .NET 3.5 considered to be an "addon" or a "silent install" or what??? Some posts refer to it as an "addon", but none of the sites advertising nLite addons mention .NET. Frequently when this question is asked, the answer is a link to a forum/site that's equally incomprehensible. For example, one of the often-referenced posts (on www.ryanvm.net) says: "No more standalone switchless. Unpack and use internal switchless. Use RVMI or Nlite to apply... " OK... exactly HOW do I "use Nlite to apply"? And WHAT is it that I'm applying? And what is "internal switchless" ??? Thanks for any help clearing my confusion... DadCat
