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:

The installer compares the current version level against the minimum

version level. If the current level is greater than or equal to the minimum

level, the installer looks 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 the current version level (all other

version fields in the .tvt filename must match the minimum version

exactly). If it does not find a file, the install process continues without

updating the Predesktop Area. If the current level is less than the

minimum level, the installer will look for a .tvt file with a compatibility

code (AA or AB). that is equal to the minimum version compatibility code

and a level that is greater than or equal to the minimum version level (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.

– Current code < Minimum code:

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.

Predesktop Area language packs (approximately 5 – 30 MB each): There are

16 language packs for Windows PE that are supported in Rescue and

Recovery 4.1. Each language pack is named in the format

Z501ZABXXXXCC00.tvt where XXXX is the build ID and CC represents the

language. One of these files is required if the Predesktop Area is being

installed on a non-English system or a system with a non-supported

language and must be in the same directory as the main installation and the

US Predesktop Area .tvt file. If the Predesktop Area is being installed or

updated and a language pack is required, the installation looks for the

minimum level of language pack required in a version file contained within
