    Laughable, because you need to keep one system exclusively for this with the recommended versions. When any of these multiple software owners issue an update, you no longer can service on MCA portel. In a free world, using multiple software and insisting users to have system requirements of given denomination is simply ridiculous. Nobody is setting any standards for software updates and MCA does not guarantee automatic upgrades. Result chaos!
