Hi All,

Below is my code for uninstallation.

C#

private void Uninstall()
       {
           try
           {
               string[] arguments = Environment.GetCommandLineArgs();
               foreach (string argument in arguments)
               {
                   if (argument.Split('=')[0].ToLower() == "/u")
                   {
                       string guid = argument.Split('=')[1];
                       string path = Environment.GetFolderPath(Environment.SpecialFolder.System);
                       ProcessStartInfo si = new ProcessStartInfo(path + "/msiexec.exe", "/x " + guid);
                       Process.Start(si);
                       Close();
                       Application.Exit();
                   }
               }
           }
           catch (Exception ex)
           {
               DataClass.LogError(ex);
           }
       }

When i am going to uninstall the application
i am getting Visual studio don't send Error message.

DSIL has encountered a problem and needs to close. We are sorry for the inconvenience.

Pawan.

The error you described, i believe that its due to early return of your application.

While uninstalling it is advisable to wait for the process to complete its execution.
The example you have given, closes and exits the application thread, which of course invalidates the uninstall process.
Try using

C#

ProcessStartInfo startInfo = new ProcessStartInfo(
    "cmd.exe",
    string.Format("/c start /MIN /wait msiexec.exe /x {0} /quiet", guid));
startInfo.WindowStyle = ProcessWindowStyle.Hidden;

Process process = Process.Start(startInfo);
process.WaitForExit();

Dear GpuToaster,

still i am getting Visual studio don't send Error message.

private void Uninstall()
{
try
{
string[] arguments = Environment.GetCommandLineArgs();
foreach (string argument in arguments)
{
if (argument.Split('=')[0].ToLower() == "/u")
{
string guid = argument.Split('=')[1];
string path = Environment.GetFolderPath(Environment.SpecialFolder.System);
ProcessStartInfo si = new ProcessStartInfo("cmd.exe", string.Format("/c start /MIN /wait msiexec.exe /x {0} /quiet", guid));
si.WindowStyle = ProcessWindowStyle.Hidden;
Process process=Process.Start(si);
process.WaitForExit();
//Close();
//Application.Exit();
}
}
}
catch (Exception ex)
{
DataClass.LogError(ex);
}
}

just place the System.Environment.Exit(0); after Application.Exit(); it works fine and no Don't Send error.

private void Uninstall()
{
try
{
string[] arguments = Environment.GetCommandLineArgs();
foreach (string argument in arguments)
{
if (argument.Split('=')[0].ToLower() == "/u")
{
string guid = argument.Split('=')[1];
string path = Environment.GetFolderPath(Environment.SpecialFolder.System);
ProcessStartInfo si = new ProcessStartInfo(path + "/msiexec.exe", "/i " + guid);
Process.Start(si);
Close();
Application.Exit();

System.Environment.Exit(0);

}
}
}
catch (Exception ex)
{
DataClass.LogError(ex);
}
}
