Pervasive/Btrieve status (error) code 20. Error code 20 is often experienced by end users. The cause depends in part on the Btrieve/Pervasive environment in which the software is running. Btrieve 6.15 systems.

While some people have reported financial success in getting Btrieve 6.15 to work on modern systems like Windows 7, many have not been able to get it to work, mostly due to the new security implemented in some of these newer operating systems.

The database engine then calls various Win32 system libraries to perform image operations on the database files. The Windows client version of Btrieve could access the server versions of Btrieve through a DOS-based “requester”.

An attempt to create a Btrieve file based on existing Btrieve information will return this status. The key buffer in the Btrieve build reliability API (opcode 14) is set to correctly create a file on top of an existing file.
