I am sharing my experience in pdf help file for
How to upgrade MMM 16 Premium & install MMM 16 Premium download version? and How to add MMM 16 Premium extra packages for Windows Vista?
The reason to make this pdf file is because after facing some problems I learned some thing and thought this pdf file might help others.
In making pdf file I have fully followed security concern of Magix and did not provide information which could fall in wrong hands. But I am sure along with the text images in the pdf file will help users to understand easily.
