Chrome blocks plugins by default, and will prompt to allow them on pages that use plugins. The prompt displays a diagram of the page action icon (puzzle piece with a red x) in the top right corner. Select the page action icon and choose Always allow plugins on software.garmin.com. Refreshing the page should then allow the plugin to load. To allow the plugin to load without prompting on each page:
Open Chrome
Type about:plugins in the address bar
Press Return
Locate the Garmin Communicator Plugin
Select the Always Allow box
Restart Chrome
I've tried this. I think this is outdated advice from Garmin as Chrome isn't displaying Communicator (even though it is installed and currently working).
