Dose AD still support it MM?

Cant seam to get MM installed?????  I have treid to install the software many times over the last couple of years but after installation it seems to not have been installed.  This has happened ever time Ive tried to installed it. I dont get a icon on desktop, I cant find it via windows serch, its not in the programs/apps list ,not on my desktop, it dose not auoto launch, I dont get it. Can somone help me get this resolved. I need to use it for STL repair I have some really bad meshes I need to fix for printing.
