I am running a legacy btrieve application with no support from the defunct vendor. The system is running fine on a W2K server and NT desktops but will not even install on XP (Btrieve error 11 - error file could not be located). Eventually, WBT32 causes a General Protection Fault.

I have read some things that hint that moving a copy of WBT32RES.dll from the server to the desktop System folder will do it but so far I have not found the right combination, I guess, because it still does not work.

The alternatives are very expensive (replacing the application). Any help is appreciated!

Have you looked into upgrading the underlying DB engine to PSQL (which is the successor to, and 98% compatable with, Btrieve)? YOu can download a test desktop installation from theri web site:
