A big thanks to you for all the help. I installed the said libraries, etc, etc, and WordPerfect is now installed and up and running.
For the information of other beginners, the installation files should be dumped in a subdirectory, not the root directory, and then all goes fine. Do you think I can delete all the directories it created for the installation? (not the WordPerfect directory of course.) I suppose these might have been left behind because of my multiple attempts to install the programme? Thanks again, David
