256986 Description of the Microsoft Windows registry





SYMPTOMS
When you run an application on a computer that has Windows Internet Explorer 7 installed, you receive an error message that resembles the following:

Access is denied

This problem occurs when you develop an application that starts new processes from an impersonated context.

Note This problem does not occur on a computer that has Microsoft Internet Explorer 6 installed.



CAUSE
This behavior occurs because the application calls the ShellExecuteEx function by using a thread that is running under an impersonated context. When the application calls the ShellExecuteEx function, the thread tries to access the  registry key. By design, because the thread does not have permission to access the  registry key, the application cannot call the function successfully.
