I have vista and office 2007. I created a .accdb file and wasn't able to open by clicking the icon for the file. I can goto access and open it fine. I tried to reassign the file association for accdb, but the recommended program was "2007 Microsoft Office Component". I tried to select msaccess.exe but system won't allow the association. have read other issues about word doing this for 2007. The answer is proving elusive. Any suggestions?
