I Just Tried Downloading Vegas Movie Studio on iPad, and impossible to already install on my iPad, is it possible to download, install and athis program on iPad Format or not?
Vegas Movie Studio was discontinued several years ago. During its release lifetime, it was for Windows computers/devices only.
If you are referring to a current product called Movie Studio, that will be MAGIX Movie Studio which is a completely different product to the discontinued Vegas Movie Studio. Not being a Vegas product, MAGIX Movie Studio has its own forum on MAGIX's forums at https://www.magix.info/us/video-forum/movie-studio/. If MAGIX Movie Studio is the product that you are referring to, you'll need to post your question on that forum.
