to fix the error, you need to grant the local activation permission to the component that is referred to in the error log. in the case of the error above, the component is IIS WAMREG admin service.

here are the instructions to grant the required permission to the component:

1. Open Component Services management consol. to do so on a Windows 2008 server – run the commend: comexp.msc from the Run window (or a command prompt).

or just go to Administrative tools, and select to run Component Services.

2. Select the IIS WAMREG admin Service component.

(you will find it under: Component Services \ Computer \ My Computer\ DCOM Config)
