We have 2 computers networked together. The data base files are on a windows 7 Professional 64 bit and we can't open it using a4large like we always did in previous versions of windows. However, the the other computer uses the a4large on his local drive of his windows 7 professional 32 bit and can access all the data bases from the windows 7 professional 64 bit computer. How can we resolve this issue?
