Error message 'Could not find any resources appropriate for the specified culture (or the neutral culture) on disk' after 2017 update

Hello,

I just ran an update for Studio 2017, and now when I try to open it I get this error message. I already tried following the instructions provided elsewhere, but when I get to "modules" there's no "WorldServerComponents.msi" to run.

Any ideas? I'm pretty desperate as I need to send a job off...

Best,

Neil
