"Re: Duplicating my client tax and storing the duplicated onto a 32bit database. This caused that client is marked as duplicated and unable to file"

Homebase should only be looking at one folder/directory , if you have more than 1 client file in that same folder with the same SSN you will get that "duplicate" message.

C:\ProWin19\19Data     is the default directory, do you have yours set to save to someplace else?
