So, let us come to why this error occurs. The most common cause for this error is a corrupt license. What times means is that your Windows license registry has failed to provide a valid call to your operating system to confirm the authenticity of your product.

This might happen right after a major upgrade to your operating system, due to some misplaced system files or ultimately a virus (including all sorts of ‘wares’)
