Re: No option to install Battlelog Web Plugin - can't launch Bf3 or Bf4
Your issue here is that you are trying to use a plug-in on Chrome, which Chrome does not support. Chrome dropped support for the plug-ins a while back. I love Chrome, but had to stop using it to launch the game for a while as the "Plug-in Free Launching" system has been buggy. However, a week or so ago I have been able to launch the game from Chrome with no issues, but some of my friends are still having issues with it like I was before.
If you are having issues with it, I would advise using Firefox. When you sign in, hover over your name and go to settings. The first option will be "Use Plug-in Free Game Launching", turn this OFF. Then, you will see a yellow circle with an arrow in it a little to the left of your name at the top. Click this and download and install the plug-in. After install is complete, REBOOT your PC. Try launching the game now.
If you would like to give Chrome a try and see if it will work for you like it has started for me, do the same settings as above, but make sure the plug-in free launching is ON. As I said before, it did not work for me for a long time, and suddenly started working about a week or two ago.
