I can't get BB to work on my version of Chrome. HELP!!! - Better Battlelog Forums #1902

I am currently trying to install BB to my browser and I failed. I have winrar 64 bit to open the file but when I do it does not show a install option anywhere. I have the latest version of chrome and I am not sure if that has anything to do with it or not but if anybody could please help I would really appreciate it.
Go to the download page and see how to install the plugin just below the download link.
Yea lol I just did it properly I did not read the direction's what so ever. Thank's for the reply though.
