Bug ID: 37343
           Summary: Battle.net requested update produces error after
                    restarting to allow the update
           Product: Wine
           Version: 1.7.27
          Hardware: x86-64
                OS: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: -unknown
          Assignee: [e-mail]
          Reporter: [e-mail]

I started the Battle.net launcher. The launcher displayed a dialog saying that
an update was required and it needed to restart. It displayed two buttons, a
Restart Button and an Exit Button. I clicked on the Restart button. After
clicking the restart button, the Battle.net app tried to restart to complete
the required update. Upon the restart of the Battle.net app, I receive an error
stating:

"The application failed to start because it could not find or load the Qt
platform plugin 'windows'. Reinstalling the application may fix this problem."

I had launched the Battle.net using wine64. After the error, I tried launching
the app with both wine and wine64. I receive the error no matter how it is
launched. Until today, the updates have come through fine and I have been able
to run Battle.net and World of Warcraft and World of Warcraft Beta using wine64
without any problems. The update today for Battle.net broke that and it is no
longer usable.
