I cannot install Facebook video call plug-in.
If you have problems installing Facebook Video plug-in, I advise to disable any antivirus solutions and use a compatible browser (Internet Explorer, Facebook, Chrome). Make sure that nothing interferes with the plug-in installation while you're performing it.
Nothing to do with any antivirus or browser.
The Facebook video plugin is buggy and programmed by idiots.
I can't get it to install either, and neither can lots of people on the net.
