もうネットの上で調べてもいろんな時期の情報があって混乱して困りますが.
何回インストールしてもこのざま.
「NPAPIを有効化すればいける」というのは今ではもう古い話なのか.
64-bit Chrome drops support for Google Earth Plugin - Google Earth Blog
結局, 大筋はこういう予定らしく, 消える運命なNPAPI.
April 2015
In April 2015 (Chrome 42) NPAPI support will be disabled by default in Chrome and we will unpublish extensions requiring NPAPI plugins from the Chrome Web Store. All NPAPI plugins will appear as if they are not installed, as they will not appear in the navigator.plugins list nor will they be instantiated (even as a placeholder). Although plugin vendors are working hard to move to alternate technologies, a small number of users still rely on plugins that haven’t completed the transition yet. We will provide an override for advanced users (via chrome://flags/#enable-npapi) and enterprises (via Enterprise Policy) to temporarily re-enable NPAPI (via the page action UI) while they wait for mission-critical plugins to make the transition. In addition, setting any of the plugin Enterprise policies (e.g. EnabledPlugins, PluginsAllowedForUrls) will temporarily re-enable NPAPI.
September 2015
In September 2015 (Chrome 45) we will remove the override and NPAPI support will be permanently removed from Chrome. Installed extensions that require NPAPI plugins will no longer be able to load those plugins.
