Summary: Silktest 5 installer aborts on disk space check
           Product: Wine
           Version: 0.9.38.
          Platform: Other
               URL: http://www.borland.com/us/products/silk/silktest/
        OS/Version: other
            Status: NEW
          Keywords: Installer
          Severity: normal
          Priority: P2
         Component: wine-kernel
        AssignedTo: [e-mail]
        ReportedBy: [e-mail]

The installer puts up an error dialog saying

There is not enough space on drive C:\ to extract this package.
Please free up 73.82 MB and click Retry.

in spite of C: having 8GB free.  The log shows

trace:volume:GetDiskFreeSpaceW L"C:\",0x33ef9c,0x33efa0,0x33efa8,0x33efa4
0009:Ret  KERNEL32.GetDiskFreeSpaceA() retval=00000001 ret=004013b5

Setting the windows version to win98 triggers the 2GB cap
and lets installation continue, but I suspect the 2GB cap
might be needed even on newer OS's, as MSDN says the function
can't report disk space above 2GB.
