Click Once 2010 .net 4 Windows Program Running As An Administrator?

My VB.net framework 4 windows program work fine for the users on Windows XP machines if they are in the local Administrator Group. I would like to setup this click once application to run as an administrator so the user doesn't need to be in the Administrator group. The program is reading the"C:Documents and Settings" & User & "Local SettingsTemp" folder looking for files with extension like "emf", "tmp" and "htm" and then deleting the files if they are older than 24 hours. We have a third party application that adds these file and doesn't delete them so I need the users to run this cleanup program.
