I found a workaround for the problem.

The issue is that the system updated the location of the latest wizard framework when I installed one of the .NET 3.0 tools (I'm not sure which one). The 8.0 dlls are still on the system but so are the new 9.0 dlls. For some reason (registry key or config file I think) the install is loading the 9.0 version. To get around this I put the 8.0 dlls in the GAC so .NET could find them. Then the install worked just fine. I then removed the 8.0 dlls from the GAC.

1) Start the .NET 2.0 Confiuration Utility. Start | Control Panel | Administrive Tools | Microsoft .NET Framework 2.0 Configuration

2) In the left hand tree view, open the My Computer item, and right-mouse the Assembly Cache item.

3) Click Add.. menu option

4) Select the BOTH the Microsoft.WizardFramework.dll and Microsoft.WizardFrameworkVS.dll. The are located in the Visual Studio 2005, Common, IDE directory. By default is in C:\Program Files\Microsoft Visual Studio 8\Common7\IDE. On x64 systems it's under the Program Files (x86) directory. Make sure you add both dll's to the GAC.

5) Run the install, it should work now.

6) Now remove the dll's from the GAC. In the Config Utility scroll down until you find the Microsoft.WizardFramework and right-mouse click on it. Click the Delete menu item. This will NOT "Delete" the orgianl dlls on the disk, just remove the item from the GAC. Repeat for the Microsoft.WizardFrameworkVS dll as well.
