SYMPTOMS
If you install and then remove Microsoft Visual Studio .NET 2003 on a computer that has Visual Studio .NET 2002 already installed, you may notice that the following registry entries are missing:
 * The registry entry that contains information about the type library for Vdt70p.dll:


 * The registry entry that contains information about the type library for Vdt70.dll:



CAUSE
This problem occurs because these registry entries are removed automatically when you remove Visual Studio .NET 2003.

When you install Visual Studio .NET 2003 on a computer that has Visual Studio .NET 2002 already installed, the Vdt70p.dll file and the Vdt70.dll file are updated from version 7.0.9466.0 to the version that is included with Visual Studio .NET 2003 (for example, version 7.10.2346.0). The corresponding registry entries under the TypeLib registry key are also updated. However, these updated registry entries are removed when you remove Visual Studio .NET 2003.



RESOLUTION
To resolve this problem, repair Visual Studio .NET 2002. To do this, follow these steps:
 * 1) Insert the Visual Studio .NET 2002 CD-ROM in the CD-ROM drive of your computer.
 * 2) In the Visual Studio .NET Setup dialog box, click Visual Studio .NET.
 * 3) On the Maintenance Page that appears, click Repair/Reinstall.
 * 4) When the repair has completed, click Done, and then click Exit.

When the repair has complete, you can add references to Vdt70p.dll and Vdt70.dll.



STATUS
