When I start Chrome, I still get a warning that its update failed (error code 3).
As a fix Google recommends UNinstalling Chrome, (rebooting), downloading its latest, reinstalling, and finally hoping it worked.
I tried that, but, sadly, in vain.
Then I thought, why not skip the uninstall and just install the latest setup file, i.e. ChromeStandaloneSetup64.exe, over the old one .
Well, Chrome updated just fine. Piece of Sachertorte.
In the future I’ll just keep watching Tweakers’ daily reports (for your convenience translated from Dutch) to know when to manually download and install Chrome’s latest. (Of course I don’t need translation)
