--- Comment #9 from Luca Bennati lucak3@gmail.com 2009-08-13 03:11:15 --- Created an attachment (id=23038) --> (http://bugs.winehq.org/attachment.cgi?id=23038) log of installer crash
With wine-1.1.27-126-gc92bb27
Seems like this specific issue in wintrust is fixed, because now the installer nearly finishes but crashes as in attached log.
I suggest to set fixed this bug and file another for new issue.
