256986 Description of the Microsoft Windows Registry

SYMPTOMS

When you try to install the Microsoft Visual C++ 6.0 Processor Pack on a computer that is running Microsoft Visual Studio 6.0 Service Pack 5 (SP5) and Microsoft Visual Basic 6.0 SP6, you may receive the following error message:
ERROR: This version of Processor Pack will only install on Visual C++ 6.0 Service Pack 5

CAUSE

If you upgrade from Visual Basic 6.0 SP5 to Visual Basic 6.0 SP6, the DWORD value of the latest registry entry is 6 in the following registry subkey:

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\VisualStudio\6.0\ServicePacks

When you install the Visual C++ 6.0 Processor Pack, the installer checks this registry value. Because the DWORD value of the latest registry subkey is 6, the Processor Pack is not installed successfully.

WORKAROUND

Warning If you use Registry Editor incorrectly, you may cause serious problems that may require you to reinstall your operating system. Microsoft cannot guarantee that you can solve problems that result from using Registry Editor incorrectly. Use Registry Editor at your own risk.

To work around this problem, modify the DWORD value to 5 in the latest entry of the following registry subkey:

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\VisualStudio\6.0\ServicePacks

To modify the DWORD value of the registry entry, follow these steps:
  1. Click Start, click Run, type regedit, and then press ENTER.
  2. In Registry Editor, click the following registry subkey:

    HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\VisualStudio\6.0\ServicePacks

  3. In the right pane of Registry Editor, double-click the latest entry.

    The Edit DWORD Value dialog box appears.
  4. In the Value data box, type 5, and then click OK.
  5. Exit Registry Editor.
