Mitec WRA is a great tool for registry analysis if you can find it on the Internet. The last public version was 1.5.2.0. Look for a file called WRA.zip.

Here are some quick general steps to get it to work on Linux:

1. Install Wine. For Fedora just do a yum -y install wine*
2. Install cabextract. It can be install via yum for Fedora systems.
3. Install IEs4Linux (http://www.tatanka.com.br/ies4linux/page/Main_Page). This sets up IE, which is required for WRA, and sets up a working environment for Wine.
4. Setup a bash script with the following:

#!/bin/bash

#Set the path below to reflect where you installed IES4. Take a look at the desktop icon if you are unsure
export WINEPREFIX="/home/user/.ies4linux/ie6"

#Set the path to where you have WRA.exe
wine "/appl/registry-tools/WRA.exe"
