Scripting with Scheme and Python

[edb]

Both interpreters is in PATH - I can run it by typing "python" or "gosh" in command line.
I've got a try with its path in plugin preferences and without it.
Maybe I should do something else?

Try the paths in the text boxes without double quotes.

So for example:

"C:\Program Files\...\python.exe"
changes to
C:\Program Files\...\python.exe

There shouldn't be any problems with spaces in the interpreter path.
