We told you in July about the Chrome team’s announcement last year that they planned to remove NPAPI support from Chrome by the end of 2014. This includes the Google Earth plugin that uses NPAPI.
Last week, on Tuesday, August 26, 2014, Google released a 64-bit version of Chrome which does not support 32-bit NPAPI plugins, including the Google Earth plugin. I have tried out the new 64-bit Chrome and can confirm that the plugin does not work. It does let you try to install it, but to no avail. And there are no appropriate error messages, so presumably sites using the Google Earth plugin can expect an increase in support calls.
