OK, doing this adds this path to the pythonpath. Note the setting the PYTHONPATH definitely requires 
admin  permissions because the path is written to the HKLM section in the registry.
But this call still fails:
python elyxer.py
Gives: no such file 'elyxer.py'
So PYTHONPATH is no solution.

Now I installed eLyXer as module. But when I call
python elyxer.py
I get the same error.
When I call
python -m elyxer
It works. I found out that adding a module is possible without admin permissions, but this won't 
work with my stripped-down python. But it sees that I only install it as module when Python is 
completely installed.
But please give me more time to verify this on my other test systems.

So the module solution seem to be possible!

As additional test I now added the path to the elyxer.py file to the global 
PATH variable. But
python elyxer.py
still fails.

When I only call
elyxer.py
it works, when the elyxer.py is not in a path with spaces, otherwise it fails. The -tt option is 
really needed although I don't know why.

This is the case on WinXP and also on WinXP 64-bit (aka Windows 2003).

Concerning your patch for configure.py: I get the error that the variable or command "logger" is not 
defined. But it works when I comment out the two lines containing logger.

Attached is my patch for the current configure.py file that works for me.

regards Uwe
