J'ai un error 1618 à l'installation.
Et cette histoire est ubuesque.
Il s'agit d'un problème sur une base de registre lors d'une install MSI.
Ca dit qu'une autre install est en cours et qu'il est impossible d'installer autre chose.
Je vais voir sur le support MS Windows.
Il faut un programme du type : msicuu ou msiZap 
Sauf qu'il est bien entendu impossible de les installer à cause du problème sus-cité. Bref, le serpent Microsoft se mord la queue.
Voilà, une heure que je me tape une crise de nerf. Si quelqu'un peut m'aider.
