Access is denied (Running a .bat file)

Question

This is my code to build up a .bat file and run it.

StringBuilder Batch = new StringBuilder();
Batch.AppendLine("@echo off");
Batch.AppendLine("taskkill /IM " + Process.GetCurrentProcess().ProcessName + ".exe /F");
Batch.AppendLine("ping localhost > nul");
Batch.AppendLine("del /f " +  (char)34 + Application.ExecutablePath + (char)34);
Batch.AppendLine("ren " + (char)34 + Application.StartupPath + @"\update.exe" + (char)34 + " " + Process.GetCurrentProcess().ProcessName);
Batch.AppendLine((char)34 + Application.ExecutablePath + (char)34);
Batch.AppendLine("del %0");

File.WriteAllText(Application.StartupPath + @"\update.bat", Batch.ToString(), Encoding.Default);
        Process.Start(Application.StartupPath + @"\update.bat");

However, I get access is denied, I have to run it as a admin, how can I do it?

Not an answer to your question, but I think you are not approaching it from the best direction. Instead see this question that provides a very robust answer for what you are actually trying to do: what-is-the-best-way-to-auto-update-a-windows-application

TL;DR If your original installation is "All users" then you will have problems with having to manually elevate permissions. Is the installation is "Per user" then this simplifies the permissions issue.
