Comment 4 for bug 535413

Not a problem.

It looks like Keryx isn't even getting far enough to create a logs directory.

Try running Keryx from source. You'll have to download and install Python and WxPython:
http://www.python.org/download/
http://www.wxpython.org/download.php
Then should be able to simply double-click keryx.py in the keryx\source directory.

If running from source works correctly, we'll know that it's not a problem with Keryx itself, but with the executable.
