Thanks for the report, the startup problem has been fixed, details following.

muCommander uses a library called JNA (Java Native Access) which provides access to Windows DLL and is used for certain operations like interacting with the Recycle Bin, retrieving information about volumes, etc...
This library is unfortunately not compatible yet with 64 bit versions of Windows :
https://jna.dev.java.net/issues/show_bug.cgi?id=59

I have patched muCommander to prevent the crash on startup and ensure that it falls back nicely everywhere JNA is normally used. The only inconvenience with muCommander operating sans JNA is the lack of Recycle Bin support : files can't be moved to it and you can't empty or open the Recycle Bin.

The fix is the current nightly build. Can you please download it and let me know if it starts correctly?

Thanks!

Thanks for fixing, very fast.
It works now. :)
I don't need recycle bin support so no problem at all.

[maxence@…]

Great, I'm glad that did it. Many thanks for the fast turnaround!

The JNA library has been updated to version 3.0.6 which has support for the win32_x64 architecture.
Recycle Bin support should now be functional under 64-bit versions of Windows.

When you get a chance, could you please grab the latest nightly build and confirm?
Thanks!
