Chapter 1, page 5 of the installation guide shows you the differences in what the Starter and Enterprise versions will support. It shows you that the Starter Edition will only be able to connect to a MSDE database.
You might want to do due diligence and read through the installation guide prior to attempting the installation. It informs you of the differences in steps and technologies supported for the two types of installations (enterprise as compared to the Standard/Starter installation). Having more than a few installs of Quality Center (and Test Director before that), I can say with confidence it will help you in the long run.
