Start Process as administrator

Question

I have an application(called 'Launcher'), where i can start other applications

One of this applications needs administrator-rights. If i try to launch it from the Launcher i get an exception, which says that i need higher privilege.

The code to start an application from the Launcher looks like:

try
{
   ProcessStartInfo startInfo = new ProcessStartInfo(PATH, ARGUMENT)
      {
         WorkingDirectory = WORKINGDIRECTORY
      };
   Process.Start(startInfo);
}
catch(Exception ex)
{
   MessageBox.Show(ex.Message);
}

If I start the Launcher everything works fine. But I don't want to start the Launcher as administrator every time.

How can I start the new process as administrator from a non-admin-process?

Have you looked into the app.manifest files? http://msdn.microsoft.com/en-us/library/bb756929.aspx — Mo Patel, Feb 28 '13 at 09:10
The solution with setting the Verb to "runas" doesn't work for me — Tomtom, Feb 28 '13 at 09:15

Your application needs to be admin or you need to provide a username password. For the username/password approach see:

https://groups.google.com/forum/?fromgroups=#!msg/microsoft.public.dotnet.languages.csharp/u5YuEz416R8/1oTRvUUzKj4J

And this has more of an approach you are looking for, but it's not a nice small snippet of code as you may like.

Process.Start with different credentials with UAC on

Otherwise, add this to your app manifest file.

 <requestedExecutionLevel level="requireAdministrator" uiAccess="false" />

But i don't want to run the Launcher always as administrator. – Tomtom Feb 28 '13 at 09:22
For security reasons, you can't do that without providing the username and password to the admin account. Only if the original application is admin can you use the runas verb. – corylulu Feb 28 '13 at 09:27
I thought it would be possible to start the other application as adminsitrator and then the uac-message appears? – Tomtom Feb 28 '13 at 09:30
Check my edited post. I posted links on alternative methods of doing this. None of them are very pretty though. – corylulu Feb 28 '13 at 09:31

Create an account with admin rights and then populate the UserName and Password properties on the ProcessStartInfo instance with the corresponding values for the admin account.

I can not create accounts, because the tool is executed at other computers in the network. – Tomtom Feb 28 '13 at 09:26
