I have the Sony version purchased from Amazon - the original purchase and installation predates  my Windows 10 installation.  Since upgrading the Movie Studio portion crashes (DVD Architect Studio seems ok).   It is " Sony Movie Studio Platinum" version 13 which I guess has been renamed back to "Vegas Movie Studio Platinum".   Can't seem to find a download link for updates/service packs on the Magix support website but maybe I am looking in the wrong place.
