MSI doesn't run from within C#

Question

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

Answer 1

It is also possible to execute the .msi file directly with the associated application. This happens when you set UseShellExecute to true:

Process.Start(new ProcessStartInfo() 
{ 
    FileName = @"c:\somepath\mySetup.msi", 
    UseShellExecute = true 
});

Answer 2

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?

Example: (Courtesy @Webleeuw)

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

Addition to question poster's comment on Benjamin's answer:

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