Cannot find custom tool 'custom tool' on this system

Visual Studio .NET 2003

The custom tool cannot be created by the project system. The requested custom tool will not be run because the project system has no way to instantiate it. Ensure that the custom tool is properly installed and registered.

This error may have been caused by specifying an invalid custom tool name for the CustomTool property for a particular file. It is also possible that the project file (.vbproj/.csproj) was edited, making the value for the CustomTool property invalid. Or you may be using a project developed on another computer, which has the custom tool, but the custom tool is not installed on your computer. For more information about the CustomTool property, see File Properties.

This error could also occur if CoCreateInstance fails for the custom tool. For example, it may not be registered or a required DLL may be missing.
