Kodi Krypton 17 installation troubleshooting

Hi Guys,
How are you? First of all FYI i’m not very familiar with the MAC OS environment (sorry for that)
I have a mini mac running sierra OS. I had an installation of kodi krypton ver 15.1. I received while opening Cody A message saying that the new version is available for download from Kody.TV. I downloaded from the site code krypton version 17. When I opened the installation downloaded file, I received a question asking. If to overwrite or replace the existing file. I’ve chosen mistakenly the option to replace & from that point only. Errors occurred.
Each time i click the kodi icon found in the Applications folder (kodi was mounted to application), I rcv a msg “The last time you opened Kodi, it unexpectedly quit While reopening Windows. DO you want to try to reopen its
Windows again? Choosing “Reopen” pops up a msg saying “Kodi quit unexpectedly.Click Reopen to open the application again. Click Report to see more detailed information and send a report to Apple”

All my attempts to uninstall Kodi and reinstall it again brings me exactly to the same error message “The last time you opened Kodi, it unexpectedly quit While reopening Windows. DO you want to try to reopen its
Windows again?”

Can anyone please instruct me what is required to carry on in order to install correctly Kodi ver 17.1 and launch it successfully?

Appreciate your sincere and fast response.

Regards
