I have Windows 7 and the link did not help me. I have not been able to downloads since July 2014.

You might need to enable the built-in Administrator account

open cmd (as Administrator) and type

net user administrator /active:yes

Then login with the new user and try again to Check for updates

Note: You might also need to change all your Language settings to US.

Vous pourriez avoir besoin d'activer le compte administrateur intégré

cmd ouverte (en tant qu'administrateur) et le type

net user  administrateur / active: yes

Alors connecte avec le nouvel utilisateur et essayez de nouveau pour vérifier les mises à jour

Compte administrateur activé et toujours le meme code erreur

I did this and it created a new account on my computer that I cannot delete and the update did not work for this account either
