Which of the following is NOT required for installing the RDC?

The correct choice indicates that internet access for all computers is not a strict requirement for installing the Relativity Desktop Client (RDC). While internet access can be beneficial for downloading updates, accessing certain shared resources, or obtaining support, it is not essential for the installation process itself. The installation can be performed using the RDC installer that may have been downloaded previously or shared through local network resources, meaning that a lack of internet access on some machines won’t hinder the installation.

In contrast, prerequisites must be met for the software to function correctly, access to the installer is necessary to initiate the installation, and administrative permissions are typically required to make system-wide changes, such as software installation. Thus, option A stands out as the one that is not mandatory for the installation process.
