1.) You disabled WFP via the registry key? I state very clearly that WFP remains enabled by default with my pack. The hacked DLL just gives the user the option of changing it via the registry if they so desire. 2.) I've tested the included uxtheme.dll myself and confirmed it works. Want to send the theme you're trying to use so I can test it on my end? 3.) You realize that nLite can integrate my pack directly, right? You can add the CAB like any other hotfix to be integrated (as my directions state). 1) I disabled WFP via the registry key. Your sfc_os works, but I see the WFP dialog for a few seconds, and then disappears. The other way it doesn't appears, and that's what I want. 2) I've tried with a modified Luna, modified Royale and official Royale. None of them worked. Sending you the files next weekend. 3) I know this perfectly. That's why I said that "I have problems with automatic installation". I know the situation is weird, but it's like that. I've tried twice. Gonna check again. Hope the info helps. Great work by the way Ryan. Thanks
