Welcome to the forum David. It looks like something either stopped or removed the Quality Agent from your computer. If you disabled the Quality Agent during install, this may have allowed the install without the Quality Agent. Is this a trial or academic version?
You can try to reinstall or repair the installation and see if this fixes the issue. Otherwise, contact PTC. Depending on your version, you have different routes to contact tech support.
during Creo 2.0 installation PTC Quality Agent software is automatically installed. You can see this item in Programs and Features list (available in Control Panel). You must not uninstall it, when you want to use Student edition of Creo 2.0.
