For an application using IBX you must generate a compatible client and give it the name "gds32.dll". The program instclient.exe in the \bin\ folder of your Firebird server installation should be used. There is a readme for it in the \doc\ folder. The generated DLL is what you must distribute to the users. You would need to place it in the system directory, not the application directory since, as I recall, IBX looks for the client DLL only in the system folder.

YES.

For Fb 2.0.x you need to be sure that the C runtime (msvcr71.dll) and the C++ runtime (msvcp71.dll) are in the user's system directory. Check all of the client machines.
