Simple stand alone word processor that handles VBA

I want a simple, standard, installable and stand alone Word Processor (text editor) with only the basic features of Word, but that can handle full VBA code and functionality and opens and saves *.doc, *docx, *rtf, *.html, open office documents, *.pdf. All the macro’s I’ve written and forms created should be transferable to this light weight Word Processor. Example of freeware word processors that can be used as a template: PolyEdit Lite, AbiWord or Jarte. I want to be able to update the VBA code afterwards in order to produce an update of the program. I will publish this together with some Word study documents (already made) so people without MS Word can open the documents and do some of the automated marking and copying of text. The program should run on Windows, Mac and Linux. An indication of Basic commands used in VBA that the program should be able to execute: I select text, format text: colour, bold, italic, underline (different colours) and (coloured) border, search for text or symbols, copy and paste text, create hyperlinks and follow hyperlinks (inside Word Processor and to websites), call (up) forms where all the function buttons are available, support for images, open explorer in a defined directory, open documents in a defined directory, show / hide documentmap, insert headings, turn numbering in the heading on / off.
