I can't install plugins.

So today i tried to download clownfish and a soundboard plugin() that my friends have but whenver i double click the files whcih end with a .ts3_plugin i see the plugin installator starting in my task manager but i don't see anything on my screen and after 5 seconds it dissapears on the task manager aswell, i tried to install the plugins with teamspeak closed like the installations said but then i tried to do it while ts was open and still same thing happened, i also went to my appdata and found my ts3 folder but there was no plugin folder is that the problem? i also didnt find a thing called createfileassoc.exe like i saw in some other posts
