Looks like the dependency isn't Python 3-compatible:

KoHighlights-0.5.0.0$ python3 main.py 
Traceback (most recent call last):
  File "main.py", line 17, in <module>
    from slppu import slppu as lua  # https://github.com/noembryo/slppu
  File "/home/frans/src/kobo/KoHighlights-0.5.0.0/slppu.py", line 131
    print ERRORS['unexp_end_string']
               ^
SyntaxError: Missing parentheses in call to 'print'. Did you mean print(ERRORS['unexp_end_string'])?

But other than that APPDATA thing I suspect it might pretty much just work as is.

Edit: yup, works fine.

Edit 2: except for this when double clicking on a book since os.startfile() is apparently Windows-only:

$ python main.py 
Traceback (most recent call last):
  File "main.py", line 377, in on_file_table_itemDoubleClicked
    (os.startfile(path) if isfile(path) else
AttributeError: 'module' object has no attribute 'startfile'

You can easily make it a little more generic using something like this (via):

import os, sys, subprocess

def open_file(filename):
    if sys.platform == "win32":
        os.startfile(filename)
    else:
        opener ="open" if sys.platform == "darwin" else "xdg-open"
        subprocess.call([opener, filename])
