How to get Google Chrome old versions between 46 to 49?

I need to play MP4 files which was working fine between Version 46 to 49. But since 50 there is many major bugs which i cant live with.

I can go back to Chromium but then MP4 files does not work on it, how can i therefore get Google Chrome version 46 or 47, or 48 or 49?

Please advise, i have tried many stackoverflow sites advise but they all seem to fail. can anyone show working example of real-world?

http://www.oldversion.com/windows/google-chrome/ might work

But you would need to make sure to disable the auto update, and double check as Google is very "persistent"
