Greetings, I'm Delphi expert with years of experience. I haven't worked with WPTools but have worked extensively with rtf. I can help you with this, my proposal is that I work online directly on your code, via teamviewer or RemoteDesktop. You would just need to have one PC with development IDE assigned for this task. Note that this is much easier and faster, since it may take a lot of time to build working enviroment (install necessary components and configure libraries).
Just to check about removing font decorations, do you mean, having text in one font, no colour, no bold, italic..
