Bug ID: 37354 Summary: After update, Battle.net launcher does not start in Windows 7 mode: "Cannot load Qt platform plugin Windows" Product: Wine Version: 1.7.19 Hardware: x86 OS: Linux Status: NEW Severity: normal Priority: P2 Component: -unknown Assignee: wine-bugs@winehq.org Reporter: adys.wh@gmail.com

Created attachment 49674 --> https://bugs.winehq.org/attachment.cgi?id=49674 WINEDEBUG=warn+all log

See thread on the subject: http://us.battle.net/en/forum/topic/14609931527

Setting to windows XP works (though I run into different issues then).

Error message: "This application failed to start because it could not find or load the Qt platform plugin "windows".

Reinstalling the application may fix this problem."

Attached is a warn+all which is quite telling in the files it looks for.

--- Comment #11 from Anastasius Focht focht@gmx.net --- Hello folks,

this is also needed for 'AusweisApp2 1.0.0' (german identity card app).

The installer requests 'Windows 7 SP1' minimum.

Download: https://www.ausweisapp.bund.de/download/

Can be worked around by switching to 'Windows XP' after install.

$ sha1sum AusweisApp2-1.0.0.msi d09f8c6f2cad0a089903a3e31bf96079ae3cfe59 AusweisApp2-1.0.0.msi

$ du -sh AusweisApp2-1.0.0.msi 22M AusweisApp2-1.0.0.msi

$ wine --version wine-1.7.30
