Summary: Platfrom SDK fails to install because of unhandled
                    msiexec option
           Product: Wine
           Version: 0.9.15.
          Platform: All

        OS/Version: All
            Status: NEW
          Severity: normal
          Priority: P2
         Component: wine-msi
        AssignedTo: [e-mail]
        ReportedBy: [e-mail]

Running wine PSDK_x86.exe brings up a splash screen, then wine's msiexec prints
out it's legal usage.  A +process log shows that the setup is trying to call
msiexec like so:

msiexec -i
"http://download.microsoft.com/download/a/5/f/a5f0d781-e201-4ab6-8c6a-9bb4efe..."

As of now, msiexec does not handle the -i option, and changing it to /i doesn't
work because we don't try to download the msi file.  Testing is required to
determine the behavior of the -i option (unless it's already known).  In any
case, we need to implement downloading of msi files if they are not local.
