I have a 32-bit application which needs to run on a 64-bit server which already has 64-bit database installed. I therefore need to install the 32-bit OLEDB provider.
The database installation already includes the provider and I have tried to uninstall, but it still appears in the list of available providers and the registry contains references to that installation. Installing the 32-bit client version has no effect. It doesn't seem to update the registry and the provider doesn't appear in the 32-bit data link editor.
Windows 2008 R2 64-bit
Oracle DB 126.96.36.199 64-bit
Oracle client 188.8.131.522-bit.
