Why am I getting a “Btrieve version 5.10 is too old” message when I attempt to start Peachtree Accounting? Peachtree Accounting currently uses the Btrieve database engine (version 6.15). When other programs, using an older version of Btrieve (such as version 5.10), are loaded into memory first, you will get this error when attempting to start Peachtree Accounting. To correct this error, start Peachtree Accounting before starting other programs using Btrieve. For more information, dial our PeachFax service at 1-800-719-3216 and request document #36535 or search for this document number at the technical support area of Peachtree’s Internet web site.
