Hello,

Please specify, which Oracle client have you installed: x64 or x32?

It's x86

Hello,

Make sure that data about the installed Oracle client is added to the registry branch: HKEY_LOCAL_MACHINE\SOFTWARE\ORACLE; as well as to Windows environment variables. In addition, check if the Oci.dll library is available in the path specified in the registry and environment variables
