Solution 1

That's because you need to execute the installation program instead of the package itself. See this article: C# - Installing and uninstalling software[^]

Then you need to ask a question of your own, and give sufficient detail to get a more specific answer.

No, you need to start a new Quick Answers question. Go here:
http://www.codeproject.com/Questions/ask.aspx
And post as much relevant detail as you can.

Posting a different (but sort of similar) question as a comment is considered as hijacking a thread!

Solution 2

MSI files must be installed via the MSIEXEC.EXE and you cannot call the *.msi file directly using the Process.Start().

Try the following :

C#

myProcess.StartInfo.FileName = "MSIEXEC.EXE";
myProcess.StartInfo.Arguments = "/i /q \"" + installationPackages[i] + "\"";

no I have try it and I think you should replace the installationPackages[i] to the application name
