Logic Pro 7: "XSKey driver too old!" message during launch

Symptom
When you try to open Logic Pro 7, you get a message that the XSKey driver is too old and has to be updated.

This happens only on systems which have had Logic 5 installed but not Logic 6. In this case, the XSKey driver cannot be updated by the Logic 7 installer.

Solution
Update the XSKey driver to resolve the issue. Follow these steps:

1. Download the installer.
2. Run the XSKey.pkg Installer.
3. Restart your computer when the installation is complete.
