Summary: Spiceworks IT Desktop 2.1: Wine corrupts bitmap files
                    during extraction from installer
           Product: Wine
           Version: 0.9.60
          Platform: PC
               URL: http://spiceworks.com
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: -unknown
        AssignedTo: [e-mail]
        ReportedBy: [e-mail]

When the installer Spiceworks.exe is ran it temporarily unpacks its files into
the windows/temp directory. Among the files extracted are bmp files which are
used in the installer wizard itself, including the very first page of the
wizard.

Under Wine, most of the bitmap files get extracted in corrupted form which
results in none of the bitmaps showing up on the first page of the wizard and
some not showing up on other pages of the wizard.

Spiceworks uses an NSIS installer, the contents of which can be extracted using
7zip. I have compared the files extracted by Wine with those actually in the
installer and they are of different size and binary content which clearly
indicates corruption of data by Wine. This problem does not occur under
windows.
