Bug ID: 50056
           Summary: IrfanView 4.56 cannot load JPEG2000.dll plugin
           Product: Wine
           Version: 5.20
          Hardware: x86
                OS: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: -unknown
          Assignee: [e-mail]
          Reporter: [e-mail]
      Distribution: ---

Steps to reproduce:

1) Download and install/unpack IrfanView 4.56 32bit

https://www.irfanview.info/files/iview456_setup.exe OR
https://www.irfanview.info/files/iview456.zip

2) Unpack JPEG2000.dll to IrfanView's Plugins directory from

https://www.irfanview.info/files/iview456_plugins.zip

3) Run i_view32.exe

4) Open any image

5) Choose Save As

6) Try to choose JP2 - you'll hear a beep from the speaker - that means an
error.

If you try to save you'll get this error:

Can't load plugin "JPEG2000.dll"!

Unfortunately there are no errors logged in console, so I've no idea what's
going on.

I've tried to debug using WINEDEBUG=+all but I don't understand what's going
on.

-----

Something about how IrfanView is compiled or coded has changed recently because
IrfanView 4.54 works just fine with the same plugin.
