Fails to install for me with mono26 / wine-1.2-562-ga6203f8
Unfortunately, the installer only works with an older version of Windows Script Host, which apparently isn't available anymore (WindowsXP-Windows2000-Script56-KB917344-x86-enu.exe). I still have it in my .winetrickscache, though. This bug is still present with wine-1.3.0 and Mono 2.6.7.
