ADO-Interface not supported
Hello, I am working with Borland developer Studio 2006 (german) on a PC with MS Windows XP SP3 installed. The PC had to be installed new because the harddrive crashed. After the new installation, all ADO-components in my programs will be ignored with the message "Interface nicht unterstützt" (I think it is "Interface not supported" in English). With a "test.udl"-file on the desktop I can establish a connection to a "*.mdb"-file with the OLE Jet 4.0 driver, so I think it is not a Windows-problem, but an installation-problem of BDS, perhaps a missing registry-entry or something like this. Has anyone an idea what I can do or does anyone knows, how BDS checks for this interface? Grettings from Germany Peter

Hello, Andrew,
I have tried to reinstall MDAC 2.8, but the installation routine says, that all components are part of the
actual Windows, so there is nothing to install or reinstall. All .NET-Frameworks from Version 1.1 to 3.5
and the .NET-Framework SDK are also installed.

The problem is most likely with something installed by MDAC rather than ..NET. You could run the ComCheck tool to try to find any problems. http://support.microsoft.com/kb/307255 "Peter Hohmann" wrote in message news:85653@forums.codegear.com... >

Hi, Andrew,
it worked!
The Component Checker found some mismatches in the registry (HKEY_CLASSES_ROOT/CLSID/...). There was a wrong path to some
DLL-Files. I do not know which installation is responsible for these entries, but I will find out. This path was changed to "Common Files"
where it has to be "Gemeinsame Dateien" in the german installation of Windows. Also some DLL-Entries in the registry were wrong, they
had to be "oledb32.dll". After changing this entries to the right pathname and dll-Name, the BDS works properly with the ADO-Components.
Thank you very much, Andrew!
Best regards from Germany.
