I have a number of clients who use different databases produced by myself, using the FileMaker Runtime function. The latest runtime version was produced using FileMaker Advanced 16. Since the latest iOS update, I'm being told of an issue opening the database. On double clicking the executable file the system warns "The primary file xxxxx cannot be found and is required for this application" The user then has to locate and select the runtime file. Has anyone noticed this, and or found a solution?
