Question

I\'ve read all related topics and haven\'t found a full answer to my problem.

I would like to give full permissions to SYSTEM and Read & Execute permissions to U

Answer 1

you need to implement deferred custom action for changing permissions. c# custom action example:

[CustomAction]
public static ActionResult SetFolderPermission(Session session)
{
     string folder = session.CustomActionData["Folder"].Trim('\"');
     string sid = session.CustomActionData["SID"].Trim('\"');
     System.Security.Principal.SecurityIdentifier sidID =  new System.Security.Principal.SecurityIdentifier(sid);

     System.Security.AccessControl.DirectorySecurity ds = System.IO.Directory.GetAccessControl(folder);
     ds.AddAccessRule(new System.Security.AccessControl.FileSystemAccessRule(sidID 
                , System.Security.AccessControl.FileSystemRights.Write
                , System.Security.AccessControl.InheritanceFlags.ObjectInherit
                , System.Security.AccessControl.PropagationFlags.NoPropagateInherit
                , System.Security.AccessControl.AccessControlType.Allow));
     System.IO.Directory.SetAccessControl(folder , ds);

     return ActionResult.Success;
}

you may port that on C++, custom action must be deferred - than you must access your session properties by CustomActionData
