All of the installation files for the RDB client and auxiliary programs should be contained within a shared folder on your own network for deployment to end-user machines. For example, if the server hosting the files is called Server1 and you have RDB version 6.7, the path of the installation files in the shared folder would most likely be:
\\Server1\RDB ProNet 6.7.0.0\Release\Client
There are some pre-requisites that should be installed before the RDB client itself, and they should be installed as an Administrator or using Administrator privileges:
.NET Runtime - \Prerequisites\.Net Framework 4.52 Web Installer\
Visual C Runtime 64 bit - \Prerequisites\vcredist_x64_2012sp4\
Visual C Runtime 32 bit - \Prerequisites\vcredist_x86_2012sp4\
Crystal Reports Engine - \Prerequisites\CRforVS_redist_install_32bit_13_0_13\
To install the prerequisites, right-click each prerequisite and run as admin if the option is available. If this option is not available double-click each one and follow the steps on the screen, if there are any.
