My suspicion is that you are not distributing the runtime menu file (.rtm) for your drop down menus with your application. When you build your application, try including the .rtm file as a support file, or check out this knowledgebase and include it in a .llb with your VIs: http://digital.ni.com/public.nsf/3efedde4322fef19862567740067f3cc/79035a48fda51ec6862569ed0060ac56?OpenDocument
