Influx Admin Plugin installation fails

I tried to install Influx Admin plugin by downloading and unzipping under grafana-5.2.4\public\app\plugins folder (Windows). After i start the grafana server, i tried to add Influx Admin to my dashboard. When i try clicking on this plugin in my dashboard, i get the following error. I tried a few things but didn’t help. For example, I tried to put this plugin under \app\plugins\panel folder, too. It didn’t help. I cleared the browser cache and no help. Anyone who has idea what it doesn’t work?
