http://bugs.winehq.org/show_bug.cgi?id=21596

Summary: Windows 7 Platform SDK default install fails
           Product: Wine
           Version: 1.1.37
          Platform: x86
        OS/Version: Linux
            Status: NEW
          Keywords: download, Installer
          Severity: normal
          Priority: P2
         Component: -unknown
        AssignedTo: [e-mail]
        ReportedBy: [e-mail]

If you try to install the Windows 7 Platform SDK
without disabling some of the options, it fails.
The log shows

12:48:46 PM Thursday, February 04, 2010: SFX C:\Program Files\Microsoft
SDKs\Windows\v7.0\Setup\SFX\vcredist_x64.exe installation started with log file
C:\users\dank\Temp\Microsoft Windows SDK for Windows
7_39e84b45-3dea-4c93-b469-0bba41d4286c_SFX.log
12:48:48 PM Thursday, February 04, 2010: C:\Program Files\Microsoft
SDKs\Windows\v7.0\Setup\SFX\vcredist_x64.exe installation failed with return
code 193

and the console log shows
err:process:create_process starting 64-bit process
L"C:\135afb88bfaba38f6bfd6047\install.exe" not supported on this platform

You can get the latter error by running visual c++ 2008 64 bit runtime redist
installer yourself.

So why is the installer, on a 32 bit wine, trying to run a 64 bit installer?
