Summary: Auctiva installers fail while downloading subinstaller?
           Product: Wine
           Version: 20050930
          Platform: Other
               URL: http://download1.auctiva.com/AuctivaPowerTools402.exe
        OS/Version: other
            Status: NEW
          Keywords: download
          Severity: normal
          Priority: P2
         Component: wine-net
        AssignedTo: [e-mail]
        ReportedBy: [e-mail]

Running the installer fails with a messagebox saying
"An error occurred while downloading the file
http://www.installengine.com/cert02/isengine/isscript.msi.
What would you like to do?"

I ran 
WINEDEBUG=+wininet,+msi,+relay wine/wine AuctivaPowerTools402.exe > log 2>&1
and will attach the interesting part of the log
(from the first mention of wininet to the MessageBox).
