What to do When M15 Files Won’t Open

Why won’t your M15 file open? You’ve tried double-clicking it, but it doesn’t come up, or you see an error message. So what do you do? This is a common issue with various file extensions because many extensions can be opened by multiple programs, and many programs can open a variety of extensions. It sounds confusing, but it's a lot easier to understand than you might think!

Which program should you use?

Your computer may be trying to use the wrong program to open the M15 file, or it may not have a program installed that can open the file. There are a few different programs you can use to open M15 files, including thinEdge Model, and Apple MPEG-1 Video. Try downloading one or more of these from the manufacturer’s website.
