256986 Description of the Microsoft Windows Registry



SYMPTOMS
In the Microsoft Developer Network (MSDN) Library, the Contents window and the Index window are empty if you use the MSDN Library as an external Help system for Microsoft Visual Studio .NET.



CAUSE
This problem occurs because a bad Help collection is used to initialize the MSDN Library IDE (DExplore.exe).



RESOLUTION
Warning If you use Registry Editor incorrectly, you may cause serious problems that may require you to reinstall your operating system. Microsoft cannot guarantee that you can solve problems that result from using Registry Editor incorrectly. Use Registry Editor at your own risk.

To resolve this problem, follow these steps:  Click Start, and then click Run. In the Run dialog box, type regedit, and then click OK to start Registry Editor. In Registry Editor, locate the following key:

 Locate any subkeys that are hexadecimal DWORD values (as opposed to GUID values). The hexadecimal DWORD value may be similar to the following:

0x003

Note Only one DWORD value should appear. Rename this subkey to be a GUID value. Make sure that this new GUID value appears last in the list of GUID values.

For example, assume that the last GUID value in the list is the following:

{A18B7203-14C1-49e2-97F4-8F3E679BA52A}

Rename the subkey that you located in step 4 as the following:

{A18B7203-14C1-49e2-97F4-8F3E679BA52B} GUID

This new GUID value (the renamed subkey) is the incremented value of the GUID value that was last in the list and that now appears immediately before the new GUID value.</ol>
