You may download the Windows Btrieve Driver version 5.10. As long
as your files and DDF's are in version 5.x this will work. Download
wbtrcall.dll version 5.10 now.
If your files are version 6 then you will need to upgrade to version
6.15. You may purchase BtSearch by itself or with the 6.15 Btrieve
drivers. If you have any questions email me: Gil
