Question

TabTip.exe The requested operation require
I am trying to get TabTip to pop up when a function is called. I am trying to do this with this code in .NET Core but I get the following error:
{System.ComponentModel.Win32Exception: The requested operation requires elevation
at System.Diagnostics.Process.StartCore(ProcessStartInfo startInfo)
at myfunc() in myClass.cs:line 64}
Here is the Code
Process p = new Process();
ProcessStartInfo processStartInfo = new ProcessStartInfo(#"C:\Program Files\Common Files\microsoft shared\ink\TabTip.exe");
p.StartInfo = processStartInfo;
p.Start();
I am running Visual Studio in Administrator mode.

This is the code that I used to complete what I was trying to accomplish. I needed to copy TabTip.exe from its original location to my project's directory.
var processlist = Process.GetProcesses();
foreach (var process in processlist.Where(process => process.ProcessName == "TabTip"))
{
process.Kill();
break;
}
Process cmd = new Process();
cmd.StartInfo.FileName = "powershell";
cmd.StartInfo.RedirectStandardInput = true;
cmd.StartInfo.RedirectStandardOutput = true;
cmd.StartInfo.CreateNoWindow = true;
cmd.StartInfo.UseShellExecute = false;
cmd.Start();
cmd.StandardInput.WriteLine(".\\TabTip.exe");
cmd.StandardInput.Flush();
cmd.StandardInput.Dispose();
cmd.WaitForExit();
Debug.WriteLine(cmd.StandardOutput.ReadToEnd());
