Problem with installing MinimWatch

[Ketonjo]

Thanks BlueDog,

I've uninstalled and re-installed both Java and MinimWatch again and installed Jarfix.

It looks like I've fixed the file association (well, sort of). See attached image. The problem is that it's not an "Executable Jar File". It's just a "Jar File"". I assume this is a problem? Also, the icon next to.jar in the attached image looks like a Word icon. When I go to Program files in File Explorer, the icons next to some of the files also are Word icons. Also, I don't know why the "Date Modified" is 2015 or 2016 as I hadn't even heard of MinimServer back then!

Any other ideas?
Thanks
John
