16 Avaya Video Conferencing Manager Deployment Guide
The Avaya Video Conferencing Manager installation program installs an OpenLDAP server,
the Microsoft .NET Framework 2.0 if not already installed, and PostgreSQL v8.3. You must
be logged in as a user with administrator privileges to install these programs. Before you run
the installation program, ensure that the following prerequisites are met on the computer on
which you intend to install Avaya Video Conferencing Manager:
• You have administrator rights to install the applications.
• An existing OpenLDAP installation does not exist.
• An existing PostgreSQL installation does not exist.
• If OpenSSL exists on the server, ensure that the version is 0.9.7 or later or delete the
LIBEAY32.dll and SSLEAY32.dll files (located in the C:\windows\system32 folder).
The Avaya Video Conferencing Manager installation program installs a compatible
version of these files if OpenSSL does not exist on the server. If the Avaya Video
Conferencing Manager installation program detects an earlier version, an error message
appears indicating that you must delete the LIBEAY32.dll and SSLEAY32.dll files. When
you click OK in the message dialog box and then click Next in the installation dialog
box, the installation program quits. You must then delete the LIBEAY32.dll and
SSLEAY32.dll files and uninstall Avaya Video Conferencing Manager before running the
Avaya Video Conferencing Manager installation program again. To uninstall Avaya
Video Conferencing Manager, refer to “Removing Avaya Video Conferencing Manager”
on page 99.
Caution: If you are performing an upgrade and the Avaya Video Conferencing
Manager installation program encounters an incompatible existing version of OpenSSL,
uninstalling Avaya Video Conferencing Manager removes the installation. You cannot
continue the upgrade or return your existing Avaya Video Conferencing Manager
installation to its previous state without uninstalling Avaya Video Conferencing Manager,
reinstalling the previous version and restoring its database from a backup. If you are
planning to upgrade your Avaya Video Conferencing Manager installation, ensure that
you check for an existing OpenSSL installation before performing the upgrade. For more
information about upgrade prerequisites, refer to “Upgrading Avaya Video Conferencing
Manager” on page 25.
