Looking at bug 18114, I tried the download.

First, needs dotnet20. After using winetricks for that, the (mini)installer has
a crash when attempting to download the main installer:
wine: Unhandled page fault on read access to 0x00000004 at address 0x7e578b46
(thread 0112), starting debugger...
Unhandled exception: page fault on read access to 0x00000004 in 32-bit code
(0x7e578b46).

Backtrace:

Below hack 'fixes' it:

   if (check_object)
     MgrType = LookupObjType(object);

Still has a non-fatal crash:
