Yes Prem I had tried this.
See suppose I have tried for 10 exe then all 10 have installed successfully & I could able to see all 10 in my control panel.

So problem is not this but during installation of all 10 exe I loosing focus on writing email on Outlook.

foreach (var productpath in SelectedProducts)
{
MessageBox.Show(" Installing App"+count );
}
MessageBox.Show(" Installation is Over" );

Dialog Box hold process for your replay...
if you get " Installation is Over" then redirect your flow other process..

Prem I am not getting your answer!

"Using console print trace the loop.. by that you can get how many applications are executing outside of loop trigger some actions like MessageBox."

I am using process.WaitForExit().
So it holding the process to be complete one by one.

Can you give me code or idea how I will handle through timer & thread?

Using console print trace the loop.. by that you can get how many applications are executing outside of loop trigger some actions like MessageBox.

120 exe files.

Loop is working properly. Have you better idea for this situation.

And what you told about timer & thread use.

Can you give me some exact idea or code.

Hi Sujeet,

how many exe files you are executing through you application..
I think you have to regulate something near the syntax
foreach (var productpath in SelectedProducts)
{

Check and trace the loop that how many times executing ..

Prem I am also using backgroudworker like below:

private void backgroundWorker1_DoWork(object sender, DoWorkEventArgs e)
{
int count =0;
// SelectedProducts is list having my exe file path
   foreach (var productpath in SelectedProducts)
   {

// Prepare the process to run
ProcessStartInfo processStart = new ProcessStartInfo();
// Enter in the command line arguments, after the executable name
processStart.Arguments = "VEYSILENT";
// Enter the executable to run, including the complete path
processStart.FileName = productpath;
// Do you want to show a console window?
processStart.WindowStyle = ProcessWindowStyle.Hidden;
processStart.CreateNoWindow = true;
int exitCode;
// Run the external process & wait for it to finish
using (Process process = Process.Start(processStart))
{
process.WaitForExit();

           // Retrieve the app's exit code
exitCode = process.ExitCode;
count += 1;
// Calculate product installation %
int percentageInstallation = Convert.ToInt32((count* 100) / SelectedProducts.Count());
//Update progress bar
backgroundWorker1.ReportProgress(percentageInstallation);

}
   }
}

Now when I am running application & parallel I am writing some email through outlook in my PC. So amny times loosing focus.

So now please help me.

Hi Sujeet,,

Your are executing punch of exe files is it. That Execution is over that's why you loosing focus from the text file write.
use timer or thread to keep alive the text file write until completion of your process.
