As I understand, you are considering to apply the fix provided by another user in the following thread:
As is mentioned in the forum, once you identify the correct registry key and folder, if the value is not listed, you can create it following the instructions.
Please take into consideration that serious problems might occur if you modify the registry incorrectly by using Registry Editor or by using another method. These problems may not be fixed and might require that you reinstall the operating system. Modify the registry at your own responsibility.
