Legacy Update: Get back online, activate, and install updates on your legacy Windows PC

This update is required to develop or run solutions for the 2007 Microsoft Office system that are built using Microsoft Visual Studio 2008 Service Pack 1 (SP1).

• You must install this update on your development computer, and also on client computers, if you use Visual Studio 2008 SP1 to develop Microsoft Office solutions.
  
  This update provides bug fixes and new features, including .NET Framework Client Profile compatibility and the ability to add host controls and smart tags to documents from application-level add-ins.
  
  When you install the Visual Studio Tools for Office runtime on a non-English version of the operating system, you should also install the appropriate language pack service pack to see the text of the messages from the runtime in that language, rather than English.
