I have a Mac OS 10.6 and created an air file with database, which works perfectly on my mac. I sent the whole file folder to a friend for him to test. He has Windows XP. When he tests the file test movie for example nothing happens, not even a trace upon a button action. Also no Name-app.xml file is formed in his case. However, we have been testing other air files and they work. Does anybody know what the problem is?
