Not at all! You need to check the actual client library that is being
loaded by your application. Unless you have done something to
relocate it and use the name of the Fb 1.5.3 client (which is
fbclient.dll), your IBO app will use gds32.dll in the Windows
system32 directory. So check the properties of the file *there*.

Make certain that you also do this check on any deployed client installations!!

I'm assuming you are talking about a local client here, not a remote
one? What Protocol setting are you using?
