Hi everyone, I have searched on this forum and on Google for these answers, but I've seen so many variations, that I thought I would try and get the "definitive" answer from you wonderful, fine, intelligent people Could someone please tell me the switches for unattended (but minimal GUI - progress bar for example) installation with NO reboots of the following files in RunOnceEx: - .NET 1.1 SP1 + ASP Update (all integrated - so the file to run is netfx.msi) - .NET 3.5 SP1 FullFile (the file is dotnetfx35.exe) - 3 Updates for .NET 3.5 SP1 (filenames are all .exes, not msis) As I said, I have seen so many variations on the switches, I really don't know which ones to use. Finally, should I extract the .NET 3.5 SP1 updates and try and integrate them into the main 3.5 SP1 install, or is that asking for trouble? Many thanks! Martin Hughes
