I am trying to run an MSI file from C# using the Proces.Start method. The MSI file is fine, because I can run that normally, but when I try to run the MSI file within some C
msi files cannot run on their own. If you double click on them, Windows will start
msiexec /i PathToYour.msi
Did you try to do that explicitly?

Process p = new Process(); p.StartInfo.FileName = "msiexec"; p.StartInfo.Arguments = "/i PathToYour.msi"; p.Start();
