Problem uninstalling files associated with failed Project installa

[Alba]

My first installation of MS Project 2003 was unsuccessful – likely because I
didn’t disable the virus scan first. Attempts to reinstall (after virus scan
disabled) generate this error:

Project Professional 2003 cannot be installed when another instance of
Project Professional 2003 is already present. To install this copy of
Project Projessional 2003, first remove the previous instance of Project
Professional 2003 using Add/Remove Programs from the Control Panel.

Problem: The software is not listed under Add/Remove Programs, nor were they
located on a system-wide search.

Using "System Restore" was not helpful to other users reporting the same
problem.

How do I un-install what can’t be found?

I have read the suggestions provided on a previous thread:

1. Try searching for all copies of the Global.Mpt file and renaming or
deleting
them if you didn't save any customisation. Then try re-installing.

[My search didn’t find these files anywhere.]

2. If that doesn't work, take a backup of the registry then delete all
registry
entries for Microsoft Project and try again.

[No details were provided on how to do this. I understand that doing it
incorrectly can really mess up your computer. ]

Can you provide specific instructions for how to "take a backup of the
registry then delete all registry entries for Microsoft Project"?
