Didn't understand what you ask really. If you need a languagepack, you can simply install it directly after the netfxsp1.exe. As far as I know a languagepack cannot be 'slipstreamed' into a .NET-Adminsitrative-Install-Point. But as the resulting netfxsp1.exe runs like charm from svcpack.inf there is no problem to install the languagepack directly afterwards. But there are also localized-builds of the .NET-1.1-package, so it might be a good idea to use them instead of the default english one. But I haven't got any problems with the english-packages, even when I install a german-languagepack afterwards. Anyhow you can change the language at the microsoft-links I posted above and get the right one for you. The batch should work with every version. It might be possible to create a 7z-languagepack-installer to save some bytes. Hmm, will see if this would bring any benefit. ok i just want to have not only net. 1.1 + sp1 but with langpack too now im using rar sfx with launch.bat start /w netfx.msi /qn start /w langpack.msi /qn but with your metod size of exe is ab 1 mb lower comparing to winrar metod im asking how to using your script not only start but langpack too (msiexec.exe /i langpack.msi /qb)? koszopal
