Answer 1

You need to take ownership before you add access.

using (var user = WindowsIdentity.GetCurrent())
{
    var ownerSecurity = new FileSecurity();
    ownerSecurity.SetOwner(user.User);
    File.SetAccessControl("c:\\path\\to\\broken", ownerSecurity);

    var accessSecurity = new FileSecurity();
    accessSecurity.AddAccessRule(new FileSystemAccessRule(user.User, FileSystemRights.FullControl, AccessControlType.Allow));
    File.SetAccessControl("c:\\path\\to\\broken", accessSecurity);
}

Also if you are setting DirectorySecurity you will need this

using (var user = WindowsIdentity.GetCurrent())
{
    var ownerSecurity = new DirectorySecurity();
    ownerSecurity.SetOwner(user.User);
    Directory.SetAccessControl("c:\\path\\to\\broken", ownerSecurity);

    var accessSecurity = new DirectorySecurity();
    accessSecurity.AddAccessRule(new FileSystemAccessRule(user.User, FileSystemRights.FullControl, AccessControlType.Allow));
    Directory.SetAccessControl("c:\\path\\to\\broken", accessSecurity);
}

If that doesn't work try this
