We must be doing something else wrong as it does not work even when we change the FBClient DLL to the new 2.5 version (or with GDS32 dlls generated by the new install).

Hello Eduardo

I am using a legacy app that needs gds32.dll and the 2.1.4 shnapshot. There is a small (43k) gds32.dll included in the bin folder. I have to copy this dll and the fbclient.dll AND the three files msvcp80.dll, msvcr80.dll and the microsoft.vc80.crt.manifiest to the application folder of the legacy app. May be in 2.5 the same is true.

I didn't found any documentation about this new gds32.dll approach!

I think that your app must have access to these five components, and then can access all server versions from 1.5 through 2.5

Good whishes
