The problem is that the support department of Kohls pulls Pandigital Novel Ereader Firmware Fix from Windows Update on a regular basis. On some occasions they may install the update without any notification and on other occasions they have had no problems when it comes to updates. In addition, Microsoft has recognized this issue as well and is also working on a solution. You can read about that here.
Kohls has begun to provide full support for their PnF ereader, but you will need to be able to obtain the exact version number from Microsoft before you can obtain the full results. They are still working on providing full support for the Kohl Elegant Series and a solution for the Pandigital Novel Ereader Firmware Fix has not yet been determined. It is possible that a fix will be released in the future.
There is one thing that is known for sure and that is the fact that a fix will be provided by Microsoft as long as the problem persists. There have been many reports of users receiving the correct firmware updates and then being prompted to update again after a few weeks. This is an issue that has continued for months now and Kohls has not been notified until recently. If you own the Kohl Elegant Series and find that your computer refuses to update, be sure to make use of the Microsoft Answers support page. There are others who are experiencing the same problem as you.
