On uninstalling, I get a IOException when trying to delete a directory. 'The directory is not empty'. I tried different methods, listed below, but nothing works. The files that are left behind (and cannot be deleted) have a different owner. Files that can be deleted have owner 'SYSTEM'. Files that throw an exception have owner 'Administrators(PC_Name\Administrators)' 'System' files have been written by the installshield installer (MSI), while the other files are written by my app, launched by installshield and elevated to administrator ...
How can I force a delete of this folder / files?

{
DirectoryInfo root;
Stack<DirectoryInfo> fols;
DirectoryInfo fol;
fols = new Stack<DirectoryInfo>();
root = new DirectoryInfo(path);
fols.Push(root);
while (fols.Count > 0)
{
fol = fols.Pop();
fol.Attributes = fol.Attributes & ~(FileAttributes.Archive | FileAttributes.ReadOnly | FileAttributes.Hidden);
foreach (DirectoryInfo d in fol.GetDirectories())
{
fols.Push(d);
}
foreach (FileInfo f in fol.GetFiles())
{
f.Attributes = f.Attributes & ~(FileAttributes.Archive | FileAttributes.ReadOnly | FileAttributes.Hidden);
f.Delete();
}
}
root.Delete(true);
}
EDIT: Sorry, forgot this :
On the folder that is giving problems, on installation, I'm giving the 'Users' account full control :
System.Security.Principal.SecurityIdentifier sid = new System.Security.Principal.SecurityIdentifier(
System.Security.Principal.WellKnownSidType.BuiltinUsersSid, null);
System.Security.Principal.NTAccount acct = sid.Translate(typeof(System.Security.Principal.NTAccount))
as System.Security.Principal.NTAccount;
string usr = acct.ToString();
DirectoryInfo info = new DirectoryInfo(dir);
DirectorySecurity ds = info.GetAccessControl();
ds.AddAccessRule(new FileSystemAccessRule(usr, FileSystemRights.FullControl, AccessControlType.Allow));
ds.AddAccessRule(new FileSystemAccessRule(usr, FileSystemRights.FullControl,
InheritanceFlags.ObjectInherit | InheritanceFlags.ContainerInherit, PropagationFlags.InheritOnly,
AccessControlType.Allow));
info.SetAccessControl(ds);
