Testing is complete for Graphcat 6.2 running in Corel WordPerfect X5 with the new service pack 3. That’s also known as version 15.0.0.528. There are no problems; Graphcat is totally compatible with the new release.
Installing the service pack itself wasn’t quite as routine: The service pack install failed the first time, silently. It ran, reported no problems, and finished without doing anything. The fix was to pre-install the hot fixes to X5 first, as found in the Help, Check for Updates menu item, and then run the Service Pack 3 installer again.
If in doubt, go to the Corel support pages and install any missing hot patches before installing Service Pack 3. It’s here:

In any case, after running the Service Pack installer, check the version number under ‘Help, About WordPerfect…’ When it reads 15.0.0.528, the installation has succeeded.
