I need to develop a small database that includes an attachment datatype field which means I need to develop it as an accdb file. I want to work on it both at the office, where I use a 64 bit version of MS Access 2010 and at home where I use MS Access 2007. Problem is that as soon as I do any modifications on it at work it will no longer work at home because it seems to make some modification to the file.
Is there any way I can keep an accdb file modified using 2010 from being upgraded so that I can keep using it on 2007? I don't knowingly use any features at work that aren't available on 2007.
