--- Comment #7 from Anastasius Focht focht@gmx.net 2010-01-30 07:47:28 --- Hello,
this bug also affects Windows PowerShell installer (http://appdb.winehq.org/objectManager.php?sClass=version&iId=13413), preventing it from terminating in the end. There are probably more Microsoft installers affected.
The problem and a solution is known for quite some time now, please send your patch to wine-patches for review/inclusion.
Regards
