问题 I am using WIX 3.8, Windows 8 Pro, Visual Studio 2013, and I am doing a Silent Installation. When I run with no /quiet arguments, Ir runs OK. But when I put "/quiet", nothin happend. There is some problems with /qn Arguments... Any other Arguments Runs OK. string arg = " SetupWIX.msi"; Process p = new Process(); p.StartInfo.FileName = "msiexec.exe"; p.StartInfo.CreateNoWindow = true; p.StartInfo.Arguments = "/i " + arg +" /quiet /l*v log.txt"; p.Start(); And it give error 3.
