What typically causes people uninstall MKVToolNix?

MKVToolNix is a program for converting and editing video files in the MKV format (Matroska Media Container). It is available for Windows, Linux, and Mac platforms. The program allows you to convert video files from DivX and AVI formats, as well as work with audio tracks and subtitles.

Although it is a useful tool, many new users complain about its non-user-friendly interface and the complexity of getting started.

Additionally, when you try to remove MKVToolNix, you might not find it in the list of applications, nor will you find a provided uninstaller. You may be wondering why. The reason is that MKVToolNix is not signed with a developer certificate and does not have a bundle ID record.
