You will need to trigger UAC when starting your application.

Either embed this XML in your manifest-file

<?xml version="1.0" encoding="UTF-8" standalone="yes"?>
   <assembly xmlns="urn:schemas-microsoft-com:asm.v1" manifestVersion="1.0">
     <trustInfo xmlns="urn:schemas-microsoft-com:asm.v2">
       <security>
         <requestedPrivileges>
           <requestedExecutionLevel
             level="asInvoker"
             uiAccess="false"/>
           </requestedPrivileges>
          </security>
     </trustInfo>
   </assembly>

or you can make use of this sample code from MSDN or look here or even on SO. There is plenty of stuff.
