wine-1.6-rc4 console output

I've been stuck trying to get dotnet30 installed for a while.

I thought it might be a winetricks bug but I don't think it is.
http://code.google.com/p/winetricks/issues/detail?id=263

1. winetricks -q dotnet20
2. wineboot (just in case)
3. wine netframework3.exe

Installer fails almost immediately.

I'm assuming

err:msi:ITERATE_Actions Execution halted, action
L"DD_CA_InstallXwsRegExe_X86.3643236F_FC70_11D3_A536_0090278A1BB8" returned
1603

is the relevant failure. I've ran cabextract and looked through the .msi files
with Orca but I cannot find this action, nor can I find an .exe that may
represent this action.

I'm pretty sure this never used to happen but I cannot run a bisect at the
moment because my builds are insane.

If I ever get it working I'll update with the bisect details.
