Appendix A: Uninstalling existing software
Entrust recommends that you uninstall any existing older versions of Security World
Software before you install new software. In Windows environments, if the installer
detects an existing Security World Software installation, it asks you if you want to install
the new components. These components replace your existing installation.
The automated Security World software installers do not delete user created
components, key data, or Security World data. However, on Linux, a manual installation
using .tar files does overwrite existing data and directories.
Before you uninstall the Security World Software, Entrust strongly
recommends that you make a secure backup of any existing Security
World and nShield configuration files. See the User Guide for more
information.
When upgrading the Security World Software, you do NOT need to
delete key data or any existing Security World. If you want to do so for
other reasons, see the User Guide for more information. If you do
delete Security World data, it cannot be restored unless you have an
up-to-date backup and a quorum of the Administrator Card Set (ACS)
is available.
The file nCipherKM.jar, if present, is located in the extensions folder of
your local Java Virtual Machine. The uninstall process may not delete
this file. Before reinstalling over an old installation, remove the
nCipherKM.jar file. See the User Guide for your module and operating
system for more about locating the Java Virtual Machine extensions
folder.
In Windows environments, because the hardserver is installed as a
named service (known as the nFast server), it is only possible to have
one Security World Software installation on any given computer. It is
also not possible to have more than one Security World Software
installation on the same computer on Linux.
If you are downgrading a software authenticated client to a Security
World Software earlier than version 12.60, the client will need to be re-
enrolled as software-based authentication is not supported. See the
nShield Connect User Guide, section "Configuring the nShield Connect
to use the client", for more information.
