Plug in for tutorial videos

hello everyone.
They told me to PM Little Angel for this question, but i couldnt find anywhere PM button or any kind of message so i ll ask here.
When i try to watch the tutorials it says im missing a plug in. but i dont have any choice of installing it. im using chrome. when i tried Explorer, i could see the video but no sound. there was something about Quick Time. so i downloaded it and installed it, but still i cant see any Videos with sounds.

Does anyone know what i have to do? which plug in i should use or settings i should fix?

it was about those tutorials

But today is working. looks like i had to restart my pc for some reason.
Sorry for not be more specific :slight_smile:

If anyone has the same problem with unity tutorial videos, just install Quick Time and restart.
Then when you reopen Chrome, go to video page and press “Always Run” and it will work.

P.S. Thank you for your quick reply :slight_smile:
