This is a follow-up to bug 23472, for the following installer:

sha1sum wlsetup-webc.exe
318440388b2e15c5e25948120c0fae39dab0b229  wlsetup-webc.exe

After selecting a program to install and completing the download process, the
installer fails with "an unknown error occurred". The exact procedure I've used
is this:

1. Run winetricks dotnet30
2. Set Windows version to Win7 in winecfg
3. Run the installer, selecting any one program
4. Wait for the download to complete, and the error should appear
