PRB: System Error Message "&H80004015" Running ActiveX DLL in IDE

ID: Q228487

The information in this article applies to:

Microsoft Visual Basic Learning, Professional, and Enterprise Editions for Windows, versions 5.0, 6.0

SYMPTOMS

While attempting to run an ActiveX dll from the Visual Basic IDE, the following error message is displayed:

System error &H80004015(-2147467243). The class is configured to run as a security ID different from the caller.

CAUSE

When Visual Basic runs an ActiveX dll from the IDE, it calls the CoRegisterClassObject API to temporarily register the server. This creates the AppId and specifies it to run in the Interactive User context.

The problem is due to a bug in the Microsoft OLE Libraries 4.0, which are included with the Microsoft Platform Software Development Kit (SDK). CoRegisterClassObject fails with the error message given earlier under the following conditions:

If the ActiveX server calling the API is set to run using the "Interactive User" identity.

-and-

The string associated with the following registry key contains any value other than a single valid executable name for the shell process:

HKEY_LOCAL_MACHINE\Software\Microsoft\Windows NT\CurrentVersion\Winlogon Shell=

RESOLUTION

Make certain that the HKEY_LOCAL_MACHINE\Software\Microsoft\Windows NT\CurrentVersion\Winlogon Shell= registry key contains a single valid executable name for the shell process.
