C# Application not loading on Win 10

tvkswamy

Hello,

I have written a C# WinForm application. I have put the .exe in the Program Files (x86) folder.

Later in the registry "COMPUTER\HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\WINDOWS\CURRENTVERSION\RUN" I have put my application

Value Name : ABC

Value Data : "C:\Program Files(x86)\ABC\ABC.EXE"

RegistryKey rk = Registry.LocalMachine.OpenSubKey("SOFTWARE\\Microsoft\\Windows\\CurrentVersion\\Run", true);
rk.SetValue("ABC", "\""+ Application.ExecutablePath + "\"" );

This works perfectly fine on Win 7. The application loads on startup. However in Win 10 this does not seem to load on startup.

Is there any chemical change to registry in Win 10 for applications to load on startup ? Where am I heading wrong..??

FYI :
1. User Access Control is turned off on Win 10

2. I have also tried "Current User" instead of "Local Machine" both seem to revolt from working.

Thanks for trying to help.

try to pass arguments of credentials like

Process process = new Process();
ProcessStartInfo info = new ProcessStartInfo{FileName = "notepad",
UserName = "admin",
Domain = "",
Password = "myAdminPassword",
UseShellExecute = false,
RedirectStandardOutput = true,
RedirectStandardError = true
};
process.Start(info);

Hello,

Resolved.

The problem was in the app.manifest.
<requestedExecutionLevel level="requireAdministrator" uiAccess="false" />
Once I remarked this line, the application started working on system startup.

Though my Windows User Id belongs to the Administrator group, the application does not run on startup as Administrator unlike in Win 7. Not sure why.

I remarked the line above (app.manifest) and elevated my level of access in code (to run as administrator) using the piece below
ProcessStartInfo proc = new ProcessStartInfo();
proc.UseShellExecute = true;
proc.WorkingDirectory = Environment.CurrentDirectory;
proc.FileName = Assembly.GetEntryAssembly().CodeBase;
foreach (string arg in args)
{
proc.Arguments += String.Format("\"{0}\" ", arg);
}
proc.Verb = "runas";
try         {
Process.Start(proc);
}
catch
{
Console.WriteLine("This application requires elevated credentials in order to operate correctly!");
}
I got the code piece from : https://stackoverflow.com/questions/2818179/how-do-i-force-my-net-application-to-run-as-administrator

And it now works !!

Happy Coding.
