This is browser-related error. It is the inability of your link to open a default browser due to some problem with the browser itself. It can be it is corrupted or it is not working at all.
The error message usually comes up at a point when you try to open up any link from either a package help link or within the Windows operating system on-line link.
For example, when you try to connect to a Windows personalization web page from the link provided by Microsoft at 'Personalisation' and you are prompted by a dialogue with the error message,' http://go.microsoft.com/fwlink/?Linkid=234469, Class not registered '.
