MinimWatch for Mac download unsuccessful

[DyMo]

Hi,
I'm trying to download MinimWatch latest v. for Mac (MinimWatch-0.8.5.2-macosx.dmg), but after dragging MinimWatch application disk image into my Applications folder and double-clicking the MinimWatch application to open it (also accepting and clicking Open to the Q: Are you sure you want to open it?'), nothing further happens and nothing appears on Menu bar... Java, version 8 Update 151 (build 1.8.0_151-b12), has long ago been installed and regularly auto-updated. I installed other apps lately and everything performed ok... What could be done to fix the problem? Thank you.
