--- Comment #4 from Jacek Caban jacek@codeweavers.com 2012-10-28 06:11:01 CDT --- Run Wine like this (replace setup.exe with real .exe filename if different):
WINEDEBUG=vbscript wine setup.exe &>vbscript.log
And attach vbscript.log file that will be created.
See "How do I get a debug trace?" on http://wiki.winehq.org/FAQ for details.
