BUG: Smart Tag DLL That Is Created in Visual Studio .NET 2003 Does Not Load in Office XP

When you build a Smart Tag DLL in Microsoft Visual Studio .NET 2003, the Smart Tag DLL does not load in Microsoft Office XP.

When you build a managed Smart Tag DLL in Visual Studio .NET, the Smart Tag DLL is registered for COM Interop. The Smart Tag DLL is registered at the following registry location:

HKEY_CLASSES_ROOT\CLSID\<Class ID>\InprocServer32

The <Class ID> is the Class ID of the Smart Tag Action class or the Smart Tag Recognizer class.

The Microsoft .NET Framework 1.0 sets the default value of this key to the location of Mscoree.dll. The location of Mscoree.dll includes the path. By default, this location is %SYSTEM32%\Mscoree.dll.

The .NET Framework 1.1 sets the default value of this key to Mscoree.dll without the path information. Because the registry value does not contain the path information, the Smart Tag DLL does not load when Office XP loads the Smart Tags.

Important This article contains information about modifying the registry. Before you modify the registry, make sure to back it up and make sure that you understand how to restore the registry if a problem occurs. For information about how to back up, restore, and edit the registry, click the following article number to view the article in the Microsoft Knowledge Base: To work around this problem, follow these steps:

3. In Registry Editor, locate the following key, and then click the following key:
   
   HKEY_CLASSES_ROOT\CLSID\<Class ID>\InprocServer32
   
   The <Class ID> is the Class ID of the Smart Tag Action class.
4. Click Default, and then change the default value from Mscoree.dll to C:\WINDOWS\System32\mscoree.dll for Windows XP operating systems or to C:\WINNT\System32\mscoree.dll for Microsoft Windows 2000 operating systems.
5. Repeat step 3 and step 4 for the Smart Tag Recognizer class.
