Chuck, Thanks for the info. My user isn't familiar with using Excel & ODBC but we'll give it a go. Keisuke, Thank you for responding. I was wondering about the precise situation that you discuss, that to trace the connection we must have a functional method. I did find the 32 bit ODBC driver installer finally, after looking all over for a place to download it (it is rather hidden!). So we have the driver connecting to 4D Server ok, but the actual ODBC connection fails. And I'll create a receiving method and see what we learn, but this has been pushed back a bit on the priority list so it may be a few days... Alan
