If you get an error in Visual Studio .NET 2003 every time that you hit the F1 key for context-sensitive help that says "Please Wait While Windows Configures Visual Studio .NET Enterprise Edition 2003″, then you are in luck, because I have a solution.

Normally you'd have to hit the Cancel button, or else it would give you an error about the source files being unavailable, something along the lines of "No valid source could be found for product Visual Studio .NET…"

The solution is to run the following command from a command line:

regsvr32 "C:\Program Files\Common Files\Microsoft Shared\MSDN\CookDoc.dll"

Problem solved.
