I am struggling.
Have a file in MVP format and want to edit and update.
What programs do I need for this?
Hi, and welcome to the user to user forums.
There is nothing to edit inside an MPV file. It is not a video file but an instruction set to tell a program the edits that were made to the video files within the original project. So you would need the program the MPV file was made with, along with all the original video or still image files used to create the project.

Welcome to the Magix user to user forums.
An MVP file is a Magix Video Project file, so any Magix video editing program (Movie Studio [version 18 or later], Movie Edit Pro, Video Pro X, even Photostory) will be able to open the file.
BUT, you need to be aware that it is a "project" file and does not contain any actual video, audio or image files. If you want to edit and update your video this can be done only if you also have ALL the source files (video, audio and image) also on your computer. The project file is, essentially, a database of the contents of your project and the order in which those contents are used, with what effects, for how long, etc., etc..

If you already have Movie Studio running, open your project as follows:
File>Open... then browse to your MVP, click on it, then click Open.
If Movie Studio isn't running, simply double-click on the MVP and Movie Studio will open it.
@Theodore-Coffelt Are you certain your "mvp" file was produced with Magix software. I ask because a few years ago another video editor also produced "mvp" files.
Hi
If the MVP file was created by Serif Movie Plus, then Magix Movie Studio cannot open it, you will have to use the original program which is now discontinued.

You are all so thoughtful to provide assistance.
Here is where I now sit:
I now recognize that in 2019, I used a Magix program and have upgraded this to be Movie Studio 2022 Suite.
(I am very pleased with how this video came out. The subjects, Henry and Lydia, had been married for 50 years but Henry was starting to fail. (He died last week.) Lydia arranged a 50th Anniversary celebration and asked me to produce a video using the background music "I'm Going to Love You, Like I'm Going to Lose You".) My task at hand is to update this video (fix audio, remove an old boyfriend of the daughter) in include the last 3.5 years.
Here is the YouTube link for anyone interested. 
When I try to start the Magix Movie Studio 2022 Suite, I get the following error message "The application was unable to start correctly (0xc000007b)"
Recommendations?
Hi
We need more information to help diagnose the issue you are having:
The specification of your computer system including Windows version, see this topic for what is required and please quote processor and graphics card make/model in full, and also what monitor/screen resolution(s) you are working with if this is a laptop.
I would suggest you put this information in your profile signature so we do not have to keep asking for it.
