What do I choose for the .FEY Extension Registration Question?
You may be presented with one or both of the following messages after installing and running FCS Express 5 or later for the first time on your PC:
These messages are confirmation that files with the extensions .FEY or .FE_LAUNCH are native to FCS Express.
As a result, when you try to open a file with either of these extensions, Windows will automatically associate these file extensions with FCS Express and launch FCS Express when trying to open files with these extensions.
Simply, click the checkbox for Do not attempt to register the extension again and click on Yes.
FCS Express will launch normally when opening FCS Express layouts, and you will no longer be presented with the question.
