Some users get this error, others don't. I have determined that the problem exists for users who don't have the dao350.dll and dao2535.tlb files in C:\Program Files\Common Files\Microsoft Shared\DAO. I have these two files and the 360.dll file. Apparently 350 is for Access 97, while 360 is for 2002; however these same users who have the problem were all accessing the db through the 97 version. I don't much know access or DAO, can I simply copy the 350 and 2535 files to their C:\Program Files\Common Files\Microsoft Shared\DAO directory? The application works fine regardless after they acknowledget the message "Your db_name database or project contains a missing or broken reference to the file dao2535.tlb version 3.5. Perhaps the correct way is to code around the problem, but as long as it won't corrupt the database, this is an acceptable solution for me. Please advise. This is a production database so I need to get it resolved asap.
