Upgrading to Resharper 2016.2.2 from within Visual Studio failed.

My current version is 2016.1.2, VS 2015 pro, update from within ReSharper (via ReSharper | Help | Check for Updates)

Download is no problem, but I don't know where is the downloaded file. 

After hit upgrade, it shows success very quickly, however, it actually removed all other the software which ticked upgrade from my machine except Resharper. And upgrade process actually just stopped there. 

I have to re-download the installation package again to install. 

Suggestion is DON'T upgrade from within VS. and hope Jetbrains can fix this.
