If you want to recreate the MSI as a whole, i did see a thread here once, I believe i saw it in the addons section of nlite, that did explain a process of disasembling the msi, adding your patched files, and recreating the msi. I have no knowledge of this process so you will have to search the forum and find the relevant thread yourself. I also remember it used xml files, this may assist your search criteria. shark
