The information in this article applies to:
- Microsoft Visual C++, 32-bit Enterprise Edition, version 4.2
- Microsoft Visual C++, 32-bit Professional Edition, version 4.2
-------------------------------------------------------------------------------
SYMPTOMS
========
If you install Visual C++ 4.2 over version 4.1 and then run Developer Studio,
the following error message may appear:
The requested topic does not exist. The title is in error.
CAUSE
=====
This happens because the registry key (should be all on one line):
HKEY_CURRENT_USER\SoftwareMicrosoftInfoViewer\Titles\VCBKS40.MVB\LastTopic
has the last topic from Visual C++ 4.1 which is invalid in 4.2.
This problem occurs in this release because the same book name is used in both
Visual C++ 4.2 and 4.1.
RESOLUTION
==========
- Use the help system once in Visual C++ 4.2. This overwrites the registry key.
Exit and run Developer Studio again. The error does not occur.
-or-
- The error message is harmless and can be ignored.
STATUS
======
Microsoft has confirmed this to be a bug in the Microsoft products listed at the
beginning of this article. The problem was corrected in Visual C 6.0.
