Corel Word perfect 12

If I open up Wordperfet ver 12 and go to tools> setting> File> and select Location of File. I can manually change the default location of the stored files. I have also found the registry entries were those file locations get stored as list below. I need to find a way to be able to change the default location of saved files for multiple users (appx 1000) without having to have each user manually change the location. Currently some of the user are save in c:\myfiles, other are saving in c:\wordfiles, and yet some are saving files to c:\documents and setting\username\mydocuments.  I need to standarize the location of files for all users using Corel WordPerfect version 12. I have tried to use the registry entries with the wild card of %userprofile% and that did not work. Example:...  c:\documents and setting\%userprofile%\my documents\ and that does not resolve the issue whether I configure it using the manual method listed above or make registry changes as listed below.

Does anyone know a way to force a default file location for saved files\Location of Files in corel word perfect ver 12 through a registry entry, config file or Group policy so i can force all 1000 users to save in the same location.

Thanks in Advanced
