--- Comment #1 from Lukas Sandström luksan@gmail.com 2010-02-16 05:33:54 --- Created an attachment (id=26267) --> (http://bugs.winehq.org/attachment.cgi?id=26267) console output from wine 1.1.38, PC Suite 6.011.00
I can confirm this bug with wine 1.1.38 and Sony Ericsson PC Suite 6.011.00.
The installer needs to be run in a virtual desktop, as per bug #19595.
