Using IBO4 and Delphi7 I have an app that I just copied over to my new Win7 64-bit machine.
Also copied over the firebird 2.1.3 client folder and added it to my path.

I run the application and it complains that it can not find gds32.dll. If I copy/rename fbclient.dll to gds32.dll it runs fine so it is not a Windows search problem.

I have
IBConstants.GDS_DLL set to 'fbclient.dll' as suggested.

I also looked in IB_Session.pas and saw that it is coded to look for fbclient.dll BEFORE gds32.dll anyway.

Any suggestions or explanations?

Thanks,
Clive
