Hello,
    I am using C# .Net installer to deploy my application.  However there is a prerequisite for my application.  If I don't find that application(i.e. prerequisite)  installed on target machine I invoke Setup.MSI file from my installer to install the prerequisite.  But it gives me an error saying that “Error 1500 : Another installation is still in progress. You must complete that installation before continuing this one”

i try out putting that code at several places e.g.

 public override void Commit(System.Collections.IDictionary savedState)
        {
            base.Commit(savedState);            
        }

        protected override void OnAfterInstall(System.Collections.IDictionary savedState)
        {
            base.OnAfterInstall(savedState);  
        }
        protected override void OnCommitting(System.Collections.IDictionary savedState)
        {
            base.OnCommitting(savedState);            
        }
        protected override void OnCommitted(System.Collections.IDictionary savedState)
        {
            base.OnCommitted(savedState);            
        }
        protected override void OnBeforeInstall(System.Collections.IDictionary savedState)
        {
            base.OnBeforeInstall(savedState);
           //I want to execute this part.
            ProcessStartInfo info = new ProcessStartInfo();
            info.FileName = "c:\\test.bat";
            Process p = Process.Start(info);
           
            p.WaitForExit();

            System.Console.WriteLine(p.ExitCode);
        }

Can somebody help me?
Thanks in advance.

You will be getting the error because your application is installing, and attempting to install a further MSI - Windows only allows one MSI to be installed at a time. You might be best making your additional MSI a prerequisite by customising the bootstrapper - I've never tried this, so can't really help out much, but I found this:

which looks like it covers it. I'll have to have a look at it myself sometime!
