Microsoft Access 2007 accdr扩展Vista 64位操作系统

Has anyone ever tested a Microsoft Access 2007 .accdr application on Windows Vista 64 bit version? I sell a shareware program using the Access 2007 runtime, and, for one customer with that setup, there's some kind of problem. According the user ". When I try to execute the program, it opens IE and then brings up the dialog box to either Open, Save, or Cancel the "myprogram.accdr" file. If I choose run it simply goes away and then returns back to the same question"Has anyone ever tested a Microsoft Access 2007
