These information only apply to Magento 1.

You may disable the software by doing the following.

  1. Extendware -> Manage Extensions -> Overview in your store's administrative area. 

  2. Click on the software and change the status to Disabled and click Save.

If, for some reason, this is not possible, you may disable the software by adding a non "xml" prefix to any of the extension XML files located in [Magento root]/app/etc and [Magento root]/app/etc/modules (the XML files will be prefixed with Extendware).

Finally, refresh the Magento cache.
