Bug #: 34490
           Summary: wine uninstaller does not list 64-bit wine addons
           Product: Wine
           Version: 1.7.1
          Platform: x86
        OS/Version: Linux
            Status: NEW
          Keywords: download, Installer, win64
          Severity: normal
          Priority: P2
         Component: msi
        AssignedTo: [e-mail]
        ReportedBy: [e-mail]

    Classification: Unclassified

I normally run 32-bit wine only, installed in /usr/local. I compiled wine64/32
and installed that to /opt/wine6432. I noticed, however, that the addons are
not in wine uninstaller. So:

$ rm -rf ~/.wine
$ /opt/wine6432/bin/wineboot
$ find .wine/ -iname smime3*
.wine/drive_c/windows/system32/gecko/2.21/wine_gecko/smime3.dll
.wine/drive_c/windows/syswow64/gecko/2.21/wine_gecko/smime3.dll

shows that both 32-bit and 64-bit gecko are installed. But:
$ /opt/wine6432/bin/wine uninstaller --list
{348C4E18-555F-4228-8924-15DDED955D0C}|||Wine Gecko (32-bit)

I see the same behavior in 1.4, fwiw.
