dBASE files (WHONET's primary data-storage file for many years) continue to work well for most users around the world. However, we are beginning to encounter compatibility problems on some computers in part because dBASE is such an old technology. You might receive a warning or error message like those listed below:
The most common reason for these compatibility issues is a problem with the Microsoft Access Database Engine 2016, which is needed for accessing dBASE files. WHONET attempts to install this during the installation process, and in some cases, this automatic installation is blocked by the computer or system administrator policies. In other cases, the installation works well initially, but sometime later the Access Engine may stop working because of a Windows update, Microsoft Office change, etc.
If your computer is having trouble reading your WHONET dBASE files, you can try the following procedure:
You can begin to use WHONET or BacLink to make SQLite files, which do not have the dBASE compatibility issues described above.
You can also use WHONET to convert your existing dBASE files to SQLite even without resolving any dBASE compatibility problems.
