--- Comment #3 from Matti Hämäläinen ccr@tnsp.org 2011-09-09 15:47:11 CDT --- Because the traces are large (7-8MB), I could not attach, providing links instead:
1) Installation attempt with latest Wine GIT, to a clean prefix with following native components installed via winetricks (required by Vegas): "corefonts fontfix msxml3 vcrun2005 vcrun2008 quicktime76 dotnet2" This is the installation that fails to install all components of Vegas.

2) Same as above, but with that one changeset reverted (again to a clean prefix, etc):

I hope this helps.
