SP Database Over Size 30092

SPDatabase Over Size 30092 The existing installation contains more than 4 GB of data. You must have less than 4 GB of data in order to upgrade to a stand-alone installation of this product. Either reduce the size of the existing database or migrate the existing installation to a SharePoint farm configuration, and then re-run setup.
Hi! My Microsoft Office installer showed an Error: SPDatabase Over Size. What does this mean? I looked in the Office 2010 site for the definition it is an error 30092. It says that this happens when you have less than 4 GB of data but I have more than that! What’s wrong with it?
