--- Comment #4 from Jonathan Ernst jonathan@ernstfamily.ch 2008-05-27 08:09:37 --- Created an attachment (id=13393) --> (http://bugs.winehq.org/attachment.cgi?id=13393) MSI trace after installing wsh using winetricks
Still no luck with wsh (I guess from the description that it installs jscript support too).
