            Bug ID: 38870
           Summary: regsvr32: Flags specified after the DLL file are not
                    handled
           Product: Wine
           Version: 1.7.46
          Hardware: x86
                OS: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: programs
          Assignee: wine-bugs at winehq.org
          Reporter: hugh.mcmaster at outlook.com
      Distribution: ---

MediaInfo does not follow the usual regsvr32.exe <flags> <DLL> syntax.

During install it does this: regsvr32 "C:\Program
Files\MediaInfo\MediaInfo_InfoTip.dll" /s

This prints output to the terminal, even though the /s flag should invoke
Silent mode:
  regsvr32: Failed to register DLL 'C:\Program
Files\MediaInfo\MediaInfo_InfoTip.dll'

Note that this failure is a different issue.

What makes this bug serious is the uninstall routine:

  regsvr32 "C:\Programs Files\MediaInfo\MediaInfo_InfoTip.dll" /u /s

This prints the same error in the terminal:

  regsvr32: Failed to register DLL 'C:\Program
Files\MediaInfo\MediaInfo_InfoTip.dll'

Note the issue here, though. Wine has attempted to register the DLL, not
unregister it.

MediaInfo is the only program that I currently know of using regsvr32 in this
way. There will be others.

Testers: be aware of ad-supported installer. Choose 'I do not accept' when
asked if you want to install 'One System Care'.

The bug is caused by Wine's handling of regsvr32 arguments. We process them in
a linear way, whereas Windows processes all flags first.

Using a dynamic array of char or int would probably fix the issue.
