F-AVRO75,
That is not the correct way to fix the issue, though it does work.
The correct way is mentioned multiple times in this thread and requires that you fix the 'broken' entry in your Path variable. Though it may appear to be correct in some cases, it isn't and can be fixed by the method given in one of my earlier posts. The other possibility is that your WMI installation is damaged, which is even worse since it is then likely that Windows System Restore is non-functional.
The issue is that if the file is ever updated by Microsoft in the future, your older copy in the Spybot S&D folder will not be which might cause issues with the operation of your PC.
What you have done is a 'hack' that stops the message from displaying, but doesn't really fix anything.
