Hi, new to working with MKV files, just have a quick question - am I correct in assuming that it is NOT necessary to uninstall MKVToolNix version 88.0 before installing 89.0 on top of it as an overwrite? Or am I mistaken about that? Thanks very much for any help that can be provided on this.
Welcome!
You do not have to uninstall first. The installer takes care of overwriting existing files with newer ones & removing obsolete ones, if there are any.
