It's ok now, I have solved my problem : 1. To compress with 7-Zip : dotnet11, dotnet02, dotnetfx.bat, StartX.exe This create : dotnetfx.7z 2. To create a folder containing : dotnetfx.7z, 7zs.sfx, Msistub.exe, config.txt ______ config.txt_________ ;!@Install@!UTF-8! RunProgram="dotnetfx.bat" ;!@InstallEnd@! _______________________ 3. To make in command prompt : copy /b 7zs.sfx + config.txt + dotnetfx.7z dotnetfx.exe This create dotnetfx.exe who I use to instal MS .NET Framework 1.1 SP1 and 2.0 silently.
