Installing Rescue and Recovery 4.21 with existing versions
If you are installing Rescue and Recovery 4.21 on a machine with Rescue and
Recovery 3.1 installed, you can use the over-install feature. If you are installing
Rescue and Recovery 4.21 over versions 1, 2 or 3.0, uninstall the previous version
through Windows Add/Remove programs and then install Rescue and Recovery
4.21. See “Overinstall considerations” on page 5 for more information.
Rescue and Recovery installation
The following instructions are for the files that can be downloaded separately from
the Large Enterprise individual language files download page.
1.
The main installation executable for Rescue and Recovery is:
v Z652ZISXXXXUS00.EXE for Windows XP and 2000
v Z633ZISXXXXUS00.EXE for Windows Vista
where XXXX is the build ID. This is a self-extracting installation package that
extracts the installation source files and launches the installation using the
Windows Installer. It contains the installation logic and the Windows
application files. The package does not contain any of the Predesktop Area files.
Note: Windows Vista uses a different package than Windows XP and 2000.
2. Predesktop Area US Base (approximately 135 MB): This is the password
protected zip file that contains the entire Predesktop Area US base. Its name is
in the format
v Z652ZABXXXXUS00.TVT for Windows XP and 2000
v Z633ZABXXXXUS00.TVT for Windows Vista
where AB determines the compatibility of the Predesktop Area and XXXX is
the build id. This file is required to install the Predesktop Area on all language
systems. This file must be in the same directory as the main installation
package (either installation executable or Rescue and Recovery.msi if extracted
or OEM install). The exceptions to this are if the Predesktop Area is already
installed and does not need to be upgraded or if the property PDA=0 is set on
the command line when executing the installation and the Predesktop Area
(any version) does not already exist. The installation executable contains a file
pdaversion.txt that contains the minimum version of the Predesktop Area that
can work with that version of Windows. The installation executable installer
will look for a Predesktop Area file using the following logic:
v Old Predesktop Area (Rescue and Recovery 1.0 or 2.X) exists or no
Predesktop Area exists:
The installer will look for a .tvt file with a compatibility code (for example:
AA, AB) that is equal to the minimum version compatibility code and a level
that is greater than or equal to the minimum version (all other version fields
in the .tvt filename must match the minimum version exactly). If a file is not
found meeting these criteria, the installation is halted.
v New (Rescue and Recovery 3.0 or greater) Predesktop Area exists:
The installer will compare the current Predesktop Area’s compatibility code
against the minimum version compatibility code and take the following
actions based on the results:
– Current code > Minimum code:
The installer presents a message that the current environment is not
compatible with this version of Rescue and Recovery.
– Current code = Minimum code:
