The steps below assume Visual Basic 5.0 and 6.0 are both installed on the system, as well as the Windows CE Toolkit for Visual Basic 5.0.

Start Visual Basic 6.0 and create a new AddIn Project, with its default name of "MyAddIn."
Press the F5 key to run MyAddIn.
Run a second instance of Visual Basic 6.0. The following error message appears:
'MyAddIn' Could not be loaded. Remove it from the list of available Add-Ins?
Click No.
Create a New Standard EXE project, Project1. Form1 is created by default.
Close Project1 without saving and open a New ActiveX DLL project. The ceide dialog box appears with the following text:
Run-time error '48' File Not Found: Pvbcore.dll
Click OK, and note that the ActiveX DLL project is loaded.
Close the instance of Visual Basic 6.0 that is not running the Addin project and note that an Application Error occurs.
