[解决方法]

RESOLUTION

To resolve the problem, run the Visual Studio .NET or Visual Studio 2005 repair. A repair is more effective for fixing this issue because the repair process forces registration of items that are not re-registered during an install.

To run the repair, follow these steps:

1.	On the Start menu, point to Settings, click Control Panel, and then click Add/Remove Programs.
2.	On the list of installed programs, click Visual Studio .NET or Visual Studio 2005, and then click Change.
3.	Click the second item in the 1 2 3 Visual Studio Setup dialog box.
4.	Insert the product CD. If an installation wizard starts, cancel the wizard, and then proceed with the repair as outlined in the following step. If the product CD is not inserted before the next step, the CD may not be recognized.
5.	Click Repair/Re-install, and then follow the onscreen instructions.
