Hi Could anyone explain what "vsp1cln.exe /o: Offline_Windows_directory_path" does please? Would it be possible to do the following using vlite (suppose i copied my vista dvd to "c:\vlitedVista"): 1) integrate SP1 2) run "vsp1cln.exe /o:c:\vlitedVista" 3) remove components etc.. Would the second step actually work? If not, when would u use the "/o:..." command line argument then?
