When you start Microsoft Visual Studio .NET 2002, a Microsoft Windows Installer dialog box appears. The dialog box may refer to Visual Studio .NET or to another application that installed the Microsoft Windows XP version of Mso.dll.
When you install Microsoft Office 2000 after the Windows XP version of the Mso.dll file is registered on the computer, Windows Installer removes the Mso.dll typelib registration.
When you start Visual Studio .NET, Windows Installer tries to repair the Mso.dll typelib registration, but the last product that you installed (Office 2000) is called to perform the repair. The Windows Installer detects a newer version of the DLL on the computer than the version that is included with Office 2000 and the repair process fails.
Perform a manual repair of Visual Studio .NET. To perform the repair, follow these steps:
Launch Visual Studio .NET Setup.
After Setup executes, a maintenance mode window opens. Select the appropriate repair option.
Microsoft has confirmed that this is a bug in the Microsoft products that are listed at the beginning of this article. This bug was corrected in Visual Studio .NET 2003.
