-------------------------------------------------------------------------------
The information in this article applies to:

- Microsoft Visual Basic Learning Edition for Windows, version 6.0 
- Microsoft Visual Basic Professional Edition for Windows, version 6.0 
- Microsoft Visual Basic Enterprise Edition for Windows, version 6.0 
-------------------------------------------------------------------------------

SYMPTOMS
========

When developing IIS Applications (WebClasses) on Microsoft Windows 2000, the
following error messages occurs:

  Internet Information Server or Peer Web Services version 3.0 or later must be
  installed to run WebClass.

  -or-

  Error in Loading DLL

which may then be followed by these additional error messages:

  Errors during load. Refer to 'C:\Program Files\Microsoft Visual
  Studio\VB98\Template\Projects\WebClass.log' for details.

  -and-

  'C:\Program Files\Microsoft Visual
  Studio\VB98\Template\Projects\WebClass.Dsr' could not be loaded.

CAUSE
=====

The WebClass Designer searches the registry for the Active Server Pages (ASP)
2.0 Type Library key. By default, Windows 2000 only has the registry key for the
3.0 version of the ASP Type Library. Because of this, the above error messages
occur.

RESOLUTION
==========

NOTE: The following resolution requires the use of Regtlib.exe, which is
contained in Visual Studio Service Pack 3. To obtain Visual Studio Service Pack
3, see the following Microsoft Web site:

  http://msdn.microsoft.com/vstudio/sp/vs6sp3/default.asp

Registering the ASP.tlb Type Library adds the 2.0 key to the ASP Type Library
registry entry. The asp.tlb file can be found on Disk 1 of either the
Professional or Enterprise version of Microsoft Visual Studio in the following
directory:

  Common\IDE\IDE98

Copy asp.tlb to the following directory:

  Program Files\Microsoft Visual Studio\Common\IDE\IDE98

Use the regtlib.exe file to register the ASP 2.0 Type Library.

STATUS
======

Microsoft has confirmed this to be a bug in the Microsoft products listed at the
beginning of this article. This bug was corrected in the latest service pack for
Visual Studio 6.0.

MORE INFORMATION
================

Some Microsoft applications, including Visual Studio 6.0 Service Packs 2 and 3,
register the asp.tlb 2.0 Type Library automatically. The stand-alone Visual
Basic 6.0 does not.
