--- Comment #2 from Andreas Hermann Braml andreas@braml.org 2009-06-03 18:39:38 --- Created an attachment (id=21532) --> (http://bugs.winehq.org/attachment.cgi?id=21532) wine-1.1.22-365-g1643679 +msi
I can confirm the bug in Vista mode. The install succeeds in XP mode. This is the log when run in XP mode, as reference.
In there is:
trace:msi:MSI_ProcessMessage ((nil) 0 10 L"1: SkypeOpenFirewallXP 2: failed to change firewall settings 3: ")
So perhaps it's not where the problem is in Vista mode.
