I’ve been trying to update from 160 to 162, but I keep getting the following error:
It doesn’t matter if I re-download the launcher, it’ll still give me the same error every time.
EDIT: …And by “Launcher,” I mean “Updater.” You should always say what you mean…
Yes, I actually got the same error a few times. What helped in my case was to restart Windows… as stupid as that may sound. No matter, this problem needs to be fixed at rather sooner than later. We’ll look into it.
After shutting down the computer, walking away for a minute or two, then coming back and trying it again, I still get the same message.
That’s got it. Even the shakes have stopped now! 
I also got this problem 
And daffy’ solution didn’t work ether
Me too… I’ll try reinstalling the whole game
Fixed. Disable antivirus and reinstall again (the whole game)
Ok, that was my bad, I scrubbed too many of the previous available patches. I have remedied that now. I didn’t think that there were many pre 162 people left.
