I don't know if I understand the point correctly, but I think you mean .NET Framework 1.1 Service Pack 1 right? I've successfully integrated this into my XP SP2 CD. The patch accept only /Q switch and there's no such folder to place in XPCREATE to only use /Q switch so I modify XPCREATE.CMD to add /Q switch to files from SVC-EXE (I use SVC-EXE because it installs after all hotfixes and currently I have no other file in that folder) So in XPCREATE.CMD, I change the line Removed. Copyrighted code and put downloded patch in SVC-EXE and it works fine Hope that helps
