Answer 1

You need to run your application in elevated mode (via UAC). How this can be done is shown in the above StackOverflow thread:

UAC, Vista and C# - Programatically requesting elevation

Before executing the code to switch in elevated mode you should do a check if you application is running on Vista, Windows 7 or above.

Answer 2

You should not use the root of C for an ordinary application. If you're just using it because you think it's a folder you can count on, use AppData or Temp instead. If this is not an ordinary application, but is instead an administrative application, then put a manifest on it requesting it elevate (requireAdministrator) so that it can gain access to the areas of the hard drive and registry protected by UAC.
