Red Hat-compatible Linux Installation and Removal Instructions
The following instructions are valid for CentOS 5 running the GNOME desktop environment. Instructions may differ slightly for different versions of Centos, and versions of Fedora and Red Hat Enterprise, running different desktop environments, but the principle is the same. If in doubt, consult the operating system documentation.
A host computer is the computer to be controlled, running VNC Server. A client computer is a computer to connect from, running VNC Viewer.

Installing VNC Enterprise Edition on a host computer
You can install VNC Enterprise Edition from RPM using desktop tools or at the command line. Either way, both VNC Server and fully-featured VNC Viewer are installed on the host computer. You will need to be a user with administrative privileges.
Note: Alternatively, you can install VNC Enterprise Edition from an unpackaged binary (tarball). Follow these instructions.
Using desktop tools
Open the VNC Enterprise Edition .rpm file using a package manager, and follow its instructions. If you are warned that the package is not signed, choose to install anyway.
At the command line
Type rpm -U <package>, where <package> is a relative path to the VNC Enterprise Edition .rpm file.
Unlocking VNC Server
After installation, you must enter a license key to unlock VNC Server. To do this, type vnclicense -add <key> at the command line, where <key> is a valid license key. For more information, and to see how to get a trial key, see License key FAQ.
vnclicense, type man vnclicense.
Installing fully-featured VNC Viewer on a client computer
You can install fully-featured VNC Viewer on as many Red Hat-compatible Linux client computers as you like by installing the VNC Enterprise Edition .rpm file as explained above. You will need to be a user with administrative privileges. Note that VNC Server is also installed, but you cannot use it unless you have a valid license key.
Running standalone VNC Viewer on a client computer
You are free to download standalone VNC Viewer to as many Red Hat-compatible Linux client computers as you like. To run it, double-click the downloaded file (note you may have to grant it executable permissions first). This is useful if you do not want, or have sufficient privileges, to install VNC Viewer. In addition, it is the only way to get just VNC Viewer on a Red Hat-compatible Linux client computer. Note you can also carry standalone VNC Viewer with you on a USB memory stick or similar removable storage device.
VNC Address Book is not available in standalone VNC Viewer.
Removing VNC Enterprise Edition
You can remove VNC Enterprise Edition and all supporting files using desktop tools or at the command line. Either way, you will need to be a user with administrative privileges.
Using desktop tools
Open a package manager, conduct a search for the vnc-E package, mark the package for removal, and apply the change.
At the command line
Type rpm -e vnc-E.
