Won’t start

I have a SonyVaio laptop running Win 7 SP1. I have been running Kodi Jarvis 16.1 for a few months. Decided to upgrade to Krypton 17.1. Download and install went smoothly. At the finish I clicked on Run Kodi and clicked Finish. Nothing happened. So I went to the Kodi icon and clicked it. Nothing happened. I tried Run as administrator. Nothing. So I went to the Local Disk C, went to Programs (x86), Kodi, and went to Kodi .exe and clicked. Nothing.
Does anyone have a suggestion?
