Based on your feedback and continuous confusion about what to download or install we created an additional installer for those who currently have Visual Studio 2005 Team System installed. There now is a separate add-on installer specifically for adding Visual Studio Team Edition for Database Professionals to an existing VSTS installation

Checkout: Visual Studio 2005 Team Edition for Database Professionals Add-on for Visual Studio 2005 Team Suite Edition
