Here is the listing of the files, what they do, and what you need to alter.

initialize.bat - Launches off a batch to remove our reg entries from Run and RunServices. Also, drops in a .PIF file into the Startup Directory that points to phase2a.bat, which completes the uninstall process. You will need to reboot after initialize.bat is run. 4.02 will be loaded for that session, but after the reboot, 4.02 will not load. NOTE: You will need to change the directory path at the end of this file that points to the .PIF file.

Sphase2a.bat.pif - This is a Shortcut file to phase2a.bat that drops into the Startup group. NOTE: You will need to go into the Properties of this file, and change where the CMD line point to phase2a.bat on a Network Directory.

phase2a.bat - This is the main script. This does the full deletion of 4.02 after reboot, and deletes Sphase2.bat.pif from the startup group so that it will not run anymore. This file requires NO alteration.

regedel.exe - This is a third party program that enables functions such as deletion of registry keys and values. This needs to reside in the same directory as the batch files. 

And that is it! After the final batch file run, you can go straight into a 4.5 install. Let me know if you have any issues, and I will look at them.
