for executing it still need some files which are only present in the older version of virtuemart.
This module need the virtuemart_parser.php which is not present in new versions of virtuemart.
The module is not compatible with VirtueMart 2.x, though it is fully compatible with VirtueMart 1.x. I am sorry that in your opinion, this fact means that the quality of the module is worth 1 star. I disagree, of course. Instead, I would encourage you to use the support information on my website to get in touch with me and let me know if you have a problem or question about the module, particularly with any specific suggestions, like removing the module’s dependency on a particular file.
