Summary: SnelStart installer bails out with error box
           Product: Wine
           Version: 1.1.0
          Platform: PC
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: -unknown
        AssignedTo: [e-mail]
        ReportedBy: [e-mail]

When installing the SnelStart Demo (downloadable at
http://www.snelstart.nl/download/SetupDemoSnelStart.exe), the installer first
downloads a file "dotnetfx.exe" but then fails with an error box saying "1621:
Kan de handtekening van het bestand dotnetfx.exe niet controleren." (Google
shows that the English version is "1621: Failed to verify signature of
file...").

Under Windows, the installer works.
