BF4: battlelog browser plugin doesn't install

i had the same problem, but i solved it, here is my solution: step 1- uninstall the old plugin from Control Panel\Programs\Programs and Features. step 2- go and download the latest version. step 3- if you are using google chrome as a default and have ad-block, you gonna see an icon right next to the star in the white bar like a white page with an x on it, click right click then enable plugin for this site then click done. step 4- if step 3 didn't work or u didn't find the icon just simply disable all the ad-blocks plugin then reset google chrome. i hope this work for all the people with the same problem 😉
