Tools.InstallCommunityControls错误都是因为安装了SQL Server Management Studio Express CTP

Failure to install Toolbox controls via ContentInstaller or Tools.InstallCommunityControls

If you have the SQL Server Management Studio Express CTP or SQL Server 2005, then it is overwriting some registry key settings. The workaround for this is:

1. Under HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\VisualStudio\8.0\Packages\{36839529-3AF3-47fa-8194-F4A3FA9F0ED7}, change the CodeBase value to use the Visual Studio 8.0 location, for e.g. file:///D:\Program Files\Microsoft Visual Studio 8\Common7\IDE\Microsoft.VisualStudio.ToolBoxControlInstaller.dll
2. Under HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\VisualStudio\8.0\Packages\{36839529-3AF3-47fa-8194-F4A3FA9F0ED7}\SatelliteDll, change the Path value to point to the Common7\IDE folder for e.g. D:\Program Files\Microsoft Visual Studio 8\Common7\IDE\
3. Open the Visual Studio Command Prompt and run devenv /setup
