Minimwatch Installation Failure

[Mescalito]

I have a problem.
I recently had to re-install Windows 10.
When trying to reinstall Minimwatch, the progress bar gets about a third of the way along & a window opens & informs me I have successfully installed Minimwatch.

However when I click the finish button (having ticked the "Launch Minimwatch" tickbox), all that happens is that a WinRAR page opens displaying a load of Minimwatch related files.

I have tried unpacking the files to a newly created folder called Minimwatch, but I have no clue as to how to proceed from there, as there does not appear to be any .exe files unpacked.

Can anyone help?
