Make sure you have the 32 bits Oracle Client Installed

[Halli]

Hi,
I have just set up my:
a) Windows 10 64 bit
b) Delphi Berlin v. 10.1
c) DOA components version 4.1 ( install doa41d101.exe )
d) An Oracle Instant Client 64 bits ( Thin client ).
e) My PL/SQL Developer 64 bits = this software is working OK

My problem: My Delphi project builds and runs ok, showing me data from my Oracle database.
But I want to add more columns to one TOracleDataset ( DOA )
and then as soon as I click on the dropdownbox for available dataconnections - I get this error.
My project is build in 64 bits environment, my oci.dll is a 64 bit dll ( 99% sure ) but I think DOA is complaining.

I have been doing this for years, but now is the first time I did not install a full Oracle client ( with netword/admin folders and etc ). I'm only using a thin client and it works well with PLSQL Developer,
but not with Delphi - at least not in designe mode.

Have you any idea what this is about ?

kind regards,
HH

Note that the Delphi IDE is a 32 bit application. If you want to make a design-time connection from within the 32 bit Delphi IDE, you will need to have a 32 bit Oracle Client installed. Regardless whether you are using the Win32 or Win64 target platform for your project.

Ok thanks for the reply,

About Delphi tells me it's a 64bit version, but I will try to install the 32 bit Oracle thin client:

The screenshot shows that your Windows 10 OS is 64 bit. The Delphi IDE is always 32 bit though.
