What is wrong with the following code?

ProcessStartInfo startInfo = default(ProcessStartInfo);

     startInfo = new ProcessStartInfo(SetupProgramPath)
     {
         UseShellExecute = true,
         Verb = "runas",
         WindowStyle = ProcessWindowStyle.Normal,
         CreateNoWindow = false
     };

     Process.Start(startInfo);

It is expected to prompt for credentials but nothing shows up. The system has the UAC enabled and not supposed to be changed.
I appreciate your help in this one. Thank you in advance.

What I have tried:

Have tried setting

UseShellExecute = False

Also, tried removing WindowStyle and CreateNoWindow

Nothing there that calls for elevated permissions.

A child process inherits the environment of the process that launched it. If this code you posted is being run as an administrator already the child process you launch will inherit it. There would be no need to ask for permissions because it already has them.

Now, the account running this code ... at the time this code is executed, is the account in the administrators group on the machine or in a group that is in the administrators group? Or is this a normal user account, not in the administrators group?

It is a normal user account

OK, in that case, you have to ask the user for the login credentials for the account you need to use and then pass those credentials in the ProcessStartInfo instance you created, the UserName and Password properties. You don't need the Verb "runas" line at all.
