I downloaded this plugin and tried to install it, but got this error:
Code:
calibre, version 0.7.45
ERROR: Unhandled exception: <b>InvalidPlugin</b>:No valid plugin found in /home/russ/Downloads/Extract ISBN.zip
Traceback (most recent call last):

raise InvalidPlugin(_('No valid plugin found in ')+path_to_zip_file)
InvalidPlugin: No valid plugin found in /home/russ/Downloads/Extract ISBN.zip
Ok, how to install?
