Symptom:

When using Help external (dexplore.exe) to Visual Studio 2005 Team System Community Technology Preview May 2004, the Help system appears to be stuck (you see the “Downloading...“ message in the status bar, the progress bar barely moves and the Internet Explorer icon continues to spin).

Workaround:

In "C:\Program Files\Common Files\Microsoft Shared\help whidbey\dexplore.exe.config" change the following lines:

    <supportedRuntime version="v2.0.40507" safemode="true"/>
    <requiredRuntime version="v2.0.40507" safemode="true"/>

to:

    <supportedRuntime version="v2.0.40426" safemode="true"/>
    <requiredRuntime version="v2.0.40426" safemode="true"/>
