Symptom: Customers install a book and are able to open and run it one or more times. Subsequent attempts generate Error 13 - Type Mismatch.
Cause: Windows update 8.1 has an undocumented feature whereby newly placed restrictions in the Registry cause some values, when read, to be blank - even though they were written correctly.

The issue has been resolved for all products listed below.
Follow the directions carefully.
How to fix Error 13:
Make certain that the Title and Release # (below) match what you have on your Pc. You can verify this information by launching the book and getting the Title and Release # from the splash screen. Every Release # of every book is different. If you need a Release # for your book that is not listed, please contact us and we will do our best to make it happen.
Go into your Control Panel and un-install all instances of the book in question from your Pc. FAILURE TO DO THIS WILL CAUSE THE FIX TO BE INEFFECTIVE.
Click the Install link next to the Title/Release # you need. When prompted, choose 'Run'. If Windows SmartScreen comes up, click 'More Info' and then click 'Run Anyway'.
Allow the install program through any security warnings. Once the installation starts, just follow the prompts.
Now that the book is re-installed, open it and all should be fine. If you had previously entered an unlocking code to have unlimited access, you will need to re-enter it. If you can't find it, give us a call and we will be happy to give it to you again. Our number is 800-299-0202. We are open M-F 8am - 5pm CST.
