Oracle database connection requires the installation of Oracle Client or Oracle Instant Client and Visual C++ Redistributable Packages. Instant Oracle Client is downloaded and installed automatically once you are trying to establish your first database connection. The Visual C++ Redistributable Packages are installed along with the Conquest tool installation.
You must have the internet connection on your PC so that the instant client can be downloaded automatically.
The Windows user must have administrator rights to install and update the Conquest tool.
In case the instant client or redistributable packages have not been installed automatically, you can download and install Oracle Client or Oracle Instant Client and Visual C++ Redistributable Packages manually.
Choose Oracle Client depending on the version of your Conquest tool and Windows OS.
