Summary: Test Drive: Unlimited Installer fails
           Product: Wine
           Version: CVS
          Platform: PC-x86-64
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: wine-msi
        AssignedTo: [e-mail]
        ReportedBy: [e-mail]

This seems to be a regression in todays git.
With a fresh .wine the installer pops up and want to configure the os.
When I try a second time it crashes immediately, giving following extra line:

err:msi:ITERATE_DuplicateFiles Failed to copy file L"c:\Programme\Gemeinsame
Dateien\InstallShield\Driver\11\Intel 32\IDriver.exe" ->
L"c:\Programme\Gemeinsame Dateien\InstallShield\Driver\11\Intel 32\",
