For my C# app, I don't want to always prompt for elevation on application start, but if they choose an output path that is UAC protected then I need to request elevation. So, how do I check if a path is UAC protected and then how do I request elevation mid-execution? Adrian Clark The best way to detect if they are unable to perform an action is to attempt it and catch the UnauthorizedAccessException . However as @ DannySmurf correctly points out you can only elevate a COM object or separate process. There is a demonstration application within the Windows SDK Cross Technology Samples called UAC

I need my software to be able to run as administrator on Windows Vista (if someone runs it without administrative permissions, it will crash). When launching other software, I've seen a prompt by the system like "this software will run as administrator. do you want to continue?" when the app was trying to acquire administrative privileges. How do I request administrative privileges when running an c# app on Windows Vista? manojlds Add the following to your manifest file: <requestedExecutionLevel level="requireAdministrator" uiAccess="false" /> You can also use highestAvailable for the level.

I have a program that only requires elevation to Admin on very rare occasions so I do not want to set-up my manifest to require permanent elevation. How can I Programmatically request elevation only when I need it? I am using C# WindowsPrincipal pricipal = new WindowsPrincipal(WindowsIdentity.GetCurrent()); bool hasAdministrativeRight = pricipal.IsInRole(WindowsBuiltInRole.Administrator); if (!hasAdministrativeRight) { RunElevated(Application.ExecutablePath); this.Close(); Application.Exit(); } private static bool RunElevated(string fileName) { //MessageBox.Show("Run: " + fileName);
