Hi Peter, the last version where you can run 4D Write and WritePro side by side is the 32-Bit Version of V17R4. I have used that version to let my users continue with 4D Write and alongside that rewrote all code to use WritePro so that I could switch back and forth when something did not work as expected. When everything was working I removed all old 4D Write code and switched to V18. It is A LOT of work and I´m glad I´ve got that behind me. You will have to write everything completely from scratch since WritePro uses a very different approach than 4D Write. Once you get the hang of it, it´s OK but now you have to use commands from 3 areas (WP, ST and Object commands). On the plus side: converting old Write documents to Write Pro is only one line of code. Hope this info helps a little bit.
