Plugin registration failed

I'm trying to install the game but the installer fails at 73% and shows this message:



Do i have do install something else before?

 

In case you are wondering, I already tried this:

• check that you have not locked the application plug-in in your browser
• disable all extensions to the browser (you need to put in the address bar chrome://extensions/ (for Google Chrome) or about:addons (for Mozilla Firefox))
• remove Ubar (it can be called VideoPlugin)
• make sure that 4game-service is running (you should go to the "Start" menu -> "Control Panel" -> "Task Manager" -> "Services")
• if you have the Avast antivirus, remove it and reinstall the 4game application
• if you do not have an anti-virus, check your PC with Dr. Web Cureit utility
• if you have a 64-bit browser, you should install the 32-bit one, such as Google Chrome.

 

Run installer as Administrator.
