Fastreport and IBDAC 3.5 broken?

I've upgraded my registered version of IBDAC to 3.50 today. I'm using Delphi 10 and XE.

I have FB 2.1 and IB 2009 installed.

I've updated Fastreport to 4.10 and recompiled the Demo FR4 files included with IBDAC.

Now I cannot make a connection to an existing FB database from the Data tab within FR4 using the IBDACDatabase component.

The problem is present within Delphi 2010 with a previously working report and also exists in Delphi XE with a blank report with only frxReport, frxIBDACComponents and a single IBDACDatabase component present.

In XE when I attempt to connect I get 'Unavailable database'. I can connect to the same database using TIBConnection.

Further testing suggests that IBDACDatabase component is calling GDS32.DLL by default, which is the Interbase 2009 client library - this then fails when attempting to open a database created with FB 2.1 since the ODS is not supported by Interbase 2009.

IBDACDatabase component WILL connect to a database created by IB 2009.

IBCConnection will connect to FB 2.1 or IB 2009 since it has a ClientLibrary property which allows be to set which client library to use.

It would be helpful to surface a ClientLibrary property in IBDACDatabase.

If I replace GDS323.DLL in Windows/System32 and Windows/sysWOW64 with a copy of fbclient.dll renamed to GDS32.DLL then IBDACDatabase component functions correctly. But then I lose the ability to use IB in the dataexplorer.

Thank you for information. We have reproduced this problem and fixed it. This fix will be included in the next IBDAC build.
