new version or any version will not open

Hello Kodi People. First off, I do like Kodi very much. Secondly…however, it will not open. As previous comments have stated, the new version notification came up when I opened the older version, so I followed the prompts and downloaded the new version aaaaand bupkiss. I uninstalled kodi, waited then redownloaded again, restarted computer aaaaand still bupkiss… Am at a loss as to what to do…
